Ai-Ai delas Alas on Jiro Manio: ‘Sana pinahalagahan niya ang naitulong ko’ Tobias Harris’ late 3 seals Sixers’ win over Knicks “This is the time that I give back to the fans,” Pacquiao said, adding that he’d suggested “let’s do free TV for the fans,” to Top Rank promotor Bob Arum.“I have to give a good show for them,” he added. “This is it. I’m excited.”Pacquiao (59-6-2, 38 knockouts) is defending the WBO title he won on points against Jessie Vargas last November. That was one of the two fights he’s had — the other was a points win over Tim Brady in April of last year — since he lost the 2015 mega fight to Mayweather.Legendary trainer Freddie Roach has predicted a knockout against Horn, saying Pacquiao is perfectly prepared and the fight should be “short and sweet.”READ: Pacquiao out to give former school teacher Horn a boxing lessonADVERTISEMENT Pacquiao hasn’t won by knockout since 2009, but Roach said the 38-year-old eight-division champ has knocked down sparring partners and is in vintage form.“Freddie is very happy because that snap is back, the power is there,” Pacquiao said in an interview with ESPN after the weigh-in. “I feel good. Weight is not a problem. Let’s get it on.”Roach believes Pacquiao’s boxing future depends on how the fight goes against Horn. If he were to lose, Roach said he’d likely recommend retirement. A comfortable win would add ammunition for a rematch with Mayweather.Pacquiao has more than a decade of experience in this environment, and said he likes to take on a boxer who has hometown advantage because he enjoys the extra buzz. Horn (16-0-1, 11 knockouts) is unbeaten in his 17 fights since turning pro in 2013, but has never confronted anyone of Pacquiao’s caliber.Experience, “is my advantage,” Pacquiao said. “But I want to make sure that I … use it properly and maximize it.”Pacquiao tipped the scales at 66.1 kilograms (146 pounds) on Saturday, and Horn weighed in at 63.35 kilograms (147 pounds) after shedding 3 kilograms (6.6 pounds) in recent days.Horn, a former school teacher and Olympic quarterfinalist before turning pro, said he had the reach and weight advantages over Pacquiao, and had the range of punches that could cause the Filipino great some trouble.During the week, he has talked about being disrespected amid talk of another Pacquiao-Mayweather fight, and said he had the weapons to knock out Pacquiao.“Game face is on. School is out,” Horn said. “I just keep that in my mind, what I’m going to have to do in the ring, which will upset Manny.”RELATED VIDEO Thousands join Kalibo Ati-atihan despite typhoon devastation Read Next Boxers Manny Pacquiao of the Philippines, second left, and Jeff Horn of Australia, second right, pose for a photo in Brisbane, Wednesday, June 28, 2017.

0Shares0000Toure was a surprise starter in Pep Guardiola’s line-up but scored twice as City beat Palace 2-1 away from home to stay in touch with the league leaders.MANCHESTER, United Kingdom, Nov 20- Yaya Toure says he was ‘mentally’ ready to play when he made a successful return to the Manchester City side as they beat Crystal Palace in the Premier League on Saturday.Toure was a surprise starter in Pep Guardiola’s line-up but scored twice as City beat Palace 2-1 away from home to stay in touch with the league leaders. The 33-year-old Toure, who has won every domestic trophy with the Citizens, appeared to be frozen out at the Etihad after his agent, Dimitri Seluk, had a public spat with Guardiola after Toure was left out of City’s Champions League squad.The Manchester City manager made it clear that Toure would only play in his team if his agent apologised but Seluk refused.However, Toure took it upon himself to issue an apology but was still a shock pick for the game at Selhurst Park. The former Barcelona player also thanked his teammates, who clapped him back into the dressing-room after the final whistle.Toure said after the game: “I was prepared mentally and I knew that one day my manager would need me. I was delighted to play and I am very happy to be playing football.”“My team-mates are very important to me. They have always been brilliant with me, always supportive. I always want to be there to help them. I am professional, I always want to improve my game.”0Shares0000(Visited 1 times, 1 visits today)
Share This!The Mail Bag returns with a question about if the Holidays at UOR alone are worth a trip to the parks and more in this Universal Orlando Weekly Preview!Mail BagMail bag returns after a hiatus! This week our question comes from my boss, Julia! Julia asks:If you’ve never been to UOR, and never had a desire to go, but love the holidays, is it worth doing a one-day pass just to see what UOR has for the holidays without doing any rides?It is hard to recommend any Orlando park (Disney or Universal) for one day when base one-day tickets are now running $119-125 per adult plus tax. That is a lot of dough.Pretending money is no object, yes I would recommend visiting the Universal parks for the holidays (November 17 through January 6) even if the rides are not your cup of Butterbeer. The Wizarding World of Harry Potter – Hogsmeade and Diagon Alley are decorated with holiday decorations and are fun to explore on their own. Several of the live shows feature special holiday versions, such as Celestina Warbeck and the Banshees who sing special Wizarding World holiday songs.In Islands of Adventure all of Seuss Landing is decorated for the holidays with streetmosphere Whoville residents walking around decorating. The real crown jewel at Islands is The Grinchmas Who-liday Spectacular, a half-hour live show. Combining elements from the classic animated TV special and the 2000 live action movie, the show features the classic songs and a real dog playing Max! The show is included with admission to Islands of Adventure and performs throughout the day.At Universal Studios Florida the Macy’s balloons come to Florida in Universal’s Holiday Parade featuring Macy’s. Larger than life character balloons along with brand new floats parade around the park nightly.

I don’t often get the chance to attend the Google Webmaster Central office hours livestream, but I find it helpful to watch the recording afterwards for one good tip, troubleshooting advice, or reinforcement on something I don’t work with frequently.If you’re not familiar with Google Webmaster Central office hours, they’re a weekly online YouTube livestream where you can ask Google staff and other experts questions about Google Search Console, your site, problems you’re trying to resolve. And the November 14, 2017 Google Webmaster Center office hours provided me with helpful reminders about Google’s Disavow Links tool and how it works.What is Google Disavow Links Tool?Google wants to know what your site is about. It uses links to your site (also known as backlinks) as one of a couple hundred factors to assess your site and relevancy of your content. When you have numerous spammy, paid, or low-quality links to your content, it can affect how Google assesses your site. And that impacts your PageRank. If you’ve done your best to remove spammy links, asking to have the links removed, but nothing happens, you have no control over those links. They’re causing issues for your site, what can you do? That’s where Google’s Disavow Links tool comes into play. Using the tool, you can submit links you want to disavow to Google. And they’ll take action to remove the links so they’re not considered in Google’s algorithms.It’s a two-step process where you first get a list of the spammy links to your site, then submit the list to Google.Get List of Links You Want to DisavowFrom Google’s Disavow backlinks support page, you’ll want to first log in to Google Search Console.

He talked to his local general practitioner, then to an expert who after a few weeks of impersonal tests and questions told him there was nothing wrong with him. Disheartened, Semple went online to seek out people with a similar issue and ended up finding groups and forums that led to a solution to his problem.This experience stuck with Semple, who 7 or 8 years ago launched talk.gateway, an online, internal social networking platform for the 30,000 employees of the British Broadcasting Company (BBC). Today, 23,000 BBC employees talk on the talk.gateway forums, 5,000 are using wikis to collaborate on projects, and 4-500 are blogging. Bringing social networking to the BBC seemed like the inevitable thing to do, says Semple, recalling the early days of the project. There exists a potential for collaboration over the web that didn’t exist before, according to Semple, but not everyone at the BBC agreed with him. Some at the BBC saw his project as a waste of time and he initially had to fight to get people to accept it. Semple recalled that at times forum threads would grow divisive or silly, but he encouraged people to self moderate and asked questions to elevate the discussion rather than stepping in and being the “grown-up.” The result of creating an environment where users were trusted was that they began to learn how to take responsibility for themselves.Erica Driver from Forrester Research has an excellent post about Semple where she identifies 4 lessons learned from enterprise web 2.0 adoption at the BBC.

I will be staffing the Meet The Experts event – stop by with your questions and thoughts on instrumentation! See you at IDF Sept 22-24Dave I am consistently amazed by the stories I hear from customers and in industry publications about the power issues that data centers are facing these days. Given the increased compute demand, decreasing budgets and power & cooling resource constraints, data centers simply cannot continue to operate as they have in the past. These challenges are especially true for Cloud deployments, where the sheer scale of the installations magnifies any resource utilization inefficiencies – especially power – and reduces the TCO benefits promised. Data Center Managers need new levels of understanding and control of their power resources in order to allocate capacity to seamlessly meet the needs of their customers, and instrumentation is evolving to provide those new capabilities that are required.At its core, instrumentation is all about sources of data and points on control, and can be at the individual component level, coordinated server level, aggregated group level or even integrated into the facility and building management system level. At IDF in SFO, you will see a wealth of demos and sessions that will highlight how OEMs and ISVs can use a wealth of instrumentation points – starting with Intel Xeon Processor 5500 features – to develop and deliver innovative management and power management capabilities that can be used to run a Cloud environment is a more efficient manner.

A homespun Canadian telescope could explain mysterious radio signals from the distant universe Deflected windparticles The CHIME telescope was designed to chart the structure of the universe by mapping hydrogen gas. But it may discover dozens of FRBs in its daily scans of the sky. Burst catcher So much is unknown about FRBs, including whether repeaters and single FRBs comefrom the same sources, that many possible explanations are still in play. Engine room A white dwarf, neutron star, or black hole merging with another one of these massive objects could lead to a burst. But it could not repeat. Merger A neutron star collapsing into a black hole or a star made of quarks could emit a single radio pulse. It, too, would not repeat. Collapse Giant black holes at galactic centers emit jets. Bursts could occur when a jet hits a nearby black hole or gas cloud. Galactic jets Cosmic strings, defects in the fabric of spaceleftover from the big bang, could kink and emit a radio blast. Fault in our stars Electrons in intergalactic space delay low frequencies more than high. High-frequency pulse Low-frequency pulse Milliseconds Magnetar FRBs Shots in the dark Fast radio bursts (FRBs) have puzzled theorists since their discovery in 2007. Their short duration and dispersed frequencies imply compact, distant sources. One possibility is a magnetar, a highly magnetized neutron star, the city-size cinder of an exploded star. Young magnetars blast out flares of electrons and ions. When a flare hits slower moving clouds of ions, it creates a shock wave. Electrons in the shock wave gyrate around magnetic field lines and emit alaserlike pulse of radio waves.

BICKEL/SCIENCE Edo Berger, Harvard University What they need are numbers: more events and, most important, more repeaters, which can be traced to a particular environment in a home galaxy. CHIME will deliver that by surveying the sky at high sensitivity. Its troughs don’t move, but they observe a swath of sky half a degree wide, stretching from one horizon to the other. As Earth turns, CHIME sweeps across the entire northern sky. Sarah Burke-Spolaor, an astrophysicist at West Virginia University in Morgantown, says its sensitivity and wide field of view will enable it to survey a volume of the universe 500 times bigger than the one surveyed by the Parkes radio telescope in Australia, which discovered the first FRB and 21 others. “CHIME just has access to that all day, every day,” she says.Once CHIME’s commissioning phase is over later this year, scientists think it could find as many as two dozen FRBs per day. “Within a year, it will be the dominant discoverer of FRBs,” says Harvard University astrophysicist Edo Berger.The strange-looking telescope has been a labor of love for the small team behind it—labor being the operative word. A contractor assembled the dishes, lining the troughs with a radio-reflective steel wire mesh. But everything else was painstakingly assembled by researchers from UBC, the University of Toronto, and McGill University in Montreal. That includes 1000 antennas fixed beneath the gantry at each trough’s focus, 100 kilometers of cabling, and more than 1000 computer processors that sit inside radiation-shielded shipping containers next to the dishes.”Everyone has put their hands on the telescope,” says Milutinovic, who puts in shifts monitoring it and its computer systems. It’s not just a desk job. Although he left alone two baby ospreys that nested on a tall pole near the telescope, he has called in conservationists to remove other birds that set up house in the telescope’s structure, along with the occasional rattlesnake. When a humidity sensor in one of the computer containers goes off at night, Milutinovic makes the 25-minute drive to the deserted observatory to check it out. He worries about other nocturnal visitors. “I’ve seen the tracks of coyote, and there’s a bear that hangs around here.”In a field in which front-rank telescopes cost billions, the CA$20 million CHIME looks set to have an impact out of all proportion to its price tag. “CHIME shows you can build a telescope that makes the world news pretty cheaply,” Milutinovic says.Hydrogen huntNone of that was part of CHIME’s original job description. Back in 2007, a group of cosmologists in Canada had the idea of building a cheap telescope to measure the 3D distribution across the universe of hydrogen gas clouds, which glow faintly at radio frequencies. The aim, says Keith Vanderlinde of the University of Toronto, was to map ripples in the density of matter created soon after the big bang and chart their expansion over cosmic history. A change in the expansion rate would tell researchers something about dark energy, the mysterious force thought to be accelerating the universe’s growth. “Any handle we can get on it would be a huge boon to physics,” Vanderlinde says.CHIME would also be an excellent machine for studying pulsars. Pulsars are neutron stars, dense cinders of collapsed giant stars, that shoot electromagnetic beams out of their poles while rotating like a celestial lighthouse, sometimes thousands of times per second. Astronomers on Earth detect the beams as metronomic pulses of radio waves. CHIME will monitor 10 pulsars at a time, 24 hours a day, for hiccups in their perfect timekeeping that could result when passing gravitational waves stretch intervening space.When CHIME was conceived, few people were thinking about FRBs because the first, found in 2007 in archival Parkes telescope data, was such an enigma. It had a high dispersion measure, meaning the pulse was smeared across frequencies because free electrons in intergalactic space had slowed the burst’s low-frequency radio waves disproportionately. The high dispersion measure suggested the burst came from billions of light-years away, far beyond our local group of galaxies.The pulse was still bright, implying the source’s energy was a billion times that of a pulsar pulse. Yet its short duration meant the source could be no bigger than 3000 kilometers across because signals could not cross a larger object fast enough for it to act in unison and produce a single, short pulse. A citysize pulsar could fit in that space. But how could a pulsar detonate so powerfully?Astronomers were tempted to dismiss that first burst as a mirage. But it was no anomaly: Another pulse was uncovered in Parkes archival data in 2012. Then, after an upgrade with new digital instruments, Parkes detected four more in 2013, all with high dispersion measures, suggesting cosmically distant origins. That paper “made me a believer,” says McGill astronomer Victoria Kaspi, who was working to integrate pulsar monitoring into CHIME.The paper also sparked a realization: CHIME could be adapted to look for FRBs, too. “Vicky called me up and said, ‘You know, this would also make a good FRB machine,’” recalls Ingrid Stairs, a collaborator of Kaspi’s at UBC.Unlikely partnersThe upgrade was not easy. Catching FRBs requires finer time and frequency resolution than mapping hydrogen. CHIME’s data would have to be logged every millisecond across 16,000 frequency channels, Kaspi says. To do that meant tinkering with the correlator, the fearsomely parallel computer that chomps through the 13 terabits of data streaming every second from CHIME’s 1024 antennas—comparable to global cellphone traffic.The time-critical astrophysicists needed a different output from the sensitivity-is-everything cosmologists. The cosmologists, eager to map the cosmic clouds, could get by without the extra resolution. At the end of each day, they could download data onto a hard disk and ship it to UBC for leisurely processing. But that wasn’t an option for the FRB hunters, who needed high-resolution data that would quickly overwhelm a hard drive. Kaspi and her colleagues devised algorithms to scan in real time just a few minutes of high-resolution data stored in a buffer. If an event is detected, the key 20 seconds of data around it are saved. If there’s nothing, they’re dumped. Searching for FRBs is “smash and grab science,” says team member Paul Scholz of the Dominion Radio Astrophysical Observatory in Okanagan Falls. Almost every aspect of [fast radio bursts] is in play for theorists. By Daniel CleryMar. 14, 2019 , 9:30 AM CHRISTINNE MUSCHI Victoria Kaspi, an astronomer at McGill University in Montreal, Canada, realized CHIME would be an ideal net to catch radio bursts. PENTICTON, CANADA—Reporting from the Dominion Radio Astrophysical Observatory here requires old-school techniques: pad and pen. Upon arrival, I must turn off my digital recorder and cellphone and stash them in a shielded room with a Faraday cage—a metal mesh that prevents stray electromagnetic signals from escaping. The point is to keep any interference away from the observatory’s newest radio telescope, the Canadian Hydrogen Intensity Mapping Experiment (CHIME).On a clear, cold day in January, Nikola Milutinovic stands on the vertiginous gantry that runs along the focus of one of CHIME’s four 100-meter-long, trough-shaped dishes. Milutinovic, a scientific engineer at the University of British Columbia (UBC) in Vancouver, scans their reflective surfaces for snow, which generally sifts through the metallic mesh but sometimes sticks and freezes. Snow-covered hills surround him, shielding CHIME from the cellphone towers, TV transmitters, and even microwave ovens of nearby towns. “If you switched on a cellphone on Mars, CHIME could detect it,” he says.CHIME’s quarry is neither so faint nor so close. The telescope is smaller and cheaper than other leading radio observatories. But by luck as much as design, its capabilities are just right for probing what may be the most compelling new mystery in astronomy: signals from the distant universe called fast radio bursts (FRBs). Discovered in 2007, FRBs are so bright that they stick out in the data like a peak in the nearby Canadian Rockies—so long as a telescope is watching and its electronics are fast enough to pick out the pulses, which last only a few thousandths of a second.Sign up for our daily newsletterGet more great content like this delivered right to you!Country *AfghanistanAland IslandsAlbaniaAlgeriaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBolivia, Plurinational State ofBonaire, Sint Eustatius and SabaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBritish Indian Ocean TerritoryBrunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Democratic Republic of theCook IslandsCosta RicaCote D’IvoireCroatiaCubaCuraçaoCyprusCzech RepublicDenmarkDjiboutiDominicaDominican RepublicEcuadorEgyptEl SalvadorEquatorial GuineaEritreaEstoniaEthiopiaFalkland Islands (Malvinas)Faroe IslandsFijiFinlandFranceFrench GuianaFrench PolynesiaFrench Southern TerritoriesGabonGambiaGeorgiaGermanyGhanaGibraltarGreeceGreenlandGrenadaGuadeloupeGuatemalaGuernseyGuineaGuinea-BissauGuyanaHaitiHeard Island and Mcdonald IslandsHoly See (Vatican City State)HondurasHong KongHungaryIcelandIndiaIndonesiaIran, Islamic Republic ofIraqIrelandIsle of ManIsraelItalyJamaicaJapanJerseyJordanKazakhstanKenyaKiribatiKorea, Democratic People’s Republic ofKorea, Republic ofKuwaitKyrgyzstanLao People’s Democratic RepublicLatviaLebanonLesothoLiberiaLibyan Arab JamahiriyaLiechtensteinLithuaniaLuxembourgMacaoMacedonia, The Former Yugoslav Republic ofMadagascarMalawiMalaysiaMaldivesMaliMaltaMartiniqueMauritaniaMauritiusMayotteMexicoMoldova, Republic ofMonacoMongoliaMontenegroMontserratMoroccoMozambiqueMyanmarNamibiaNauruNepalNetherlandsNew CaledoniaNew ZealandNicaraguaNigerNigeriaNiueNorfolk IslandNorwayOmanPakistanPalestinianPanamaPapua New GuineaParaguayPeruPhilippinesPitcairnPolandPortugalQatarReunionRomaniaRussian FederationRWANDASaint Barthélemy Saint Helena, Ascension and Tristan da CunhaSaint Kitts and NevisSaint LuciaSaint Martin (French part)Saint Pierre and MiquelonSaint Vincent and the GrenadinesSamoaSan MarinoSao Tome and PrincipeSaudi ArabiaSenegalSerbiaSeychellesSierra LeoneSingaporeSint Maarten (Dutch part)SlovakiaSloveniaSolomon IslandsSomaliaSouth AfricaSouth Georgia and the South Sandwich IslandsSouth SudanSpainSri LankaSudanSurinameSvalbard and Jan MayenSwazilandSwedenSwitzerlandSyrian Arab RepublicTaiwanTajikistanTanzania, United Republic ofThailandTimor-LesteTogoTokelauTongaTrinidad and TobagoTunisiaTurkeyTurkmenistanTurks and Caicos IslandsTuvaluUgandaUkraineUnited Arab EmiratesUnited KingdomUnited StatesUruguayUzbekistanVanuatuVenezuela, Bolivarian Republic ofVietnamVirgin Islands, BritishWallis and FutunaWestern SaharaYemenZambiaZimbabweI also wish to receive emails from AAAS/Science and Science advertisers, including information on products, services and special offers which may include but are not limited to news, careers information & upcoming events.Required fields are included by an asterisk(*)Just days before I visit, CHIME—still in its shakedown phase—had made global headlines for bagging 13 new FRBs, bringing the total known to more than 60. Nearly that many theories exist for explaining them. One of the few things researchers know for sure, from the nature of the pulses, is that they come from far beyond our Milky Way. But in an instant, each event is over, leaving no afterglow for astronomers to study and frustrating efforts to get a fix on their origin.Whatever generates FRBs must be compact to produce such short pulses, astronomers believe, and extremely powerful to be seen at such great distances. Think neutron stars or black holes or something even more exotic. FRBs can repeat—although strangely, only two of the dozens known appear to do so. The repetition could rule out explosions, mergers, or other one-time cataclysmic events. Or repeating and solitary FRBs could be different animals with different sources—theorists just don’t know. As test observations began in 2017, the team got twitchy about how many FRBs CHIME would see. CHIME was observing at frequencies of 400 to 800 megahertz (MHz), lower than the 1.4-gigahertz frequency used to detect most FRBs. A 300-MHz survey at a different telescope had found nothing, and another survey at 700 to 800 MHz saw just a single burst. “It was worrying, especially in the lower part of the band,” Stairs says.Those worries evaporated in July and August 2018, when the team struck gold with the 13 new FRBs, even though sections of the telescope were sporadically taken offline for adjustments. The haul, published in Nature in January, included one repeater—only the second yet discovered. Kaspi declined to provide an update on the number of FRB discoveries since last summer, citing two unpublished papers in the works. But she says CHIME is “fulfilling expectations.” “It’s a bit like drinking from a firehose, but in a good way,” she says.Theories aboundTheorists want all that CHIME will deliver, and then some. A poverty of information is allowing ideas to run riot. “Almost every aspect of FRBs is in play for theorists,” Berger says. An online catalog of FRB origin theories had 48 entries at the time of writing. Many theorists initially put forward models based on the violent collapse or merger of compact objects, including white dwarfs, neutron stars, pulsars, and black holes. But the discovery of repeaters shifted speculation to sources that would not be destroyed in the act of generating a burst.Active galactic nuclei, the supermassive black holes at the centers of galaxies, spew winds and radiation that might trigger a burst by striking nearby objects—a gas cloud, a small black hole, or a hypothetical quark star. Or the bursts might come from more speculative phenomena, such as lightning strikes in the atmospheres of neutron stars or the interaction of hypothetical dark matter particles called axions with black holes or neutron stars. Amanda Weltman, a theorist at the University of Cape Town in South Africa, does not discount even more fanciful ideas such as cosmic strings, hypothetical threadlike defects in the vacuum of space leftover from the moments after the big bang. They “could be releasing fast radio bursts in a number of ways,” she says.But as the number of detected FRBs moved from single digits into dozens, astronomers realized the bursts could be downright common, detectable by the thousands every day if the right telescopes were watching. “That’s a serious problem for a lot of models,” Berger says.FRB 121102, the first repeating event detected, may be the most revealing FRB so far. The Arecibo telescope in Puerto Rico saw its first burst in 2012, but since then dozens more have been seen coming from that spot on the sky. In 2017, the 27-dish Karl G. Jansky Very Large Array in New Mexico revealed the FRB resides in the outskirts of a distant dwarf galaxy and that the location coincides with a weak but persistent radio source. That dim radio glow may emanate from a supernova remnant—an expanding ball of gas from a stellar explosion, which could have formed a black hole or neutron star that powers the FRB. In another clue, the polarization of the FRB’s radio waves rotates rapidly, suggesting they emanate from a strong magnetic environment. Brian Metzger, a theorist at Columbia University, believes a young magnetar—a highly magnetized neutron star—resides at the center of the cloud and powers the bursts. In a scenario developed with his colleagues, its magnetic field serves as a fizzy store of energy that occasionally flares, blasting out a shell of electrons and ions at nearly the speed of light—an outburst resembling a coronal mass ejection from our sun, but on steroids. When the flare hits ion clouds leftover from previous flares, the resulting shock wave boosts the strength of the clouds’ magnetic field lines and causes electrons to spiral around them in concert. Just as synchrotrons on Earth whip electrons around racetracks to emit useful x-rays, those gyrations spawn a coherent pulse of radio waves.Magnetars are often invoked to explain such energetic events, Metzger says. “They’re a catch-all for anything we don’t understand. But here it’s kind of warranted.” CHIME team member Shriharsh Tendulkar of McGill wonders whether objects such as magnetars could explain both repeaters and single-burst FRBs. Single-burst FRBs might “start out regular as repeaters, then slow as [the source’s] magnetic field weakens,” he says.But according to Weltman, it’s too early to declare the mystery solved. “There are so many clues here, but they do not yet point to a single conclusive theoretical explanation,” she says.Knowledge in numbersAs observers amass new FRBs, different classes of events may emerge, perhaps offering clues about what triggers them. FRBs may also turn out to come from specific types of galaxies—or regions within galaxies—which could allow theorists to distinguish between active galactic nuclei and other compact objects as the sources. “We need statistics and we need context,” Metzger says.In the coming years, other FRB spotters will come online, including the Hydrogen Intensity and Realtime Analysis eXperiment in South Africa and the Deep Synoptic Array in California. With their widely spaced arrays of dishes, both facilities will precisely locate FRBs on the sky—something CHIME can’t do for now. “They’re all going for localization because they know CHIME will clean up on statistics,” Scholz says.The CHIME team, not to be outdone, is drawing up a proposal to add outriggers, smaller troughs at distances of hundreds of kilometers, which will record the same events from a different angle and so help researchers pinpoint them. “With all these new efforts, there’ll be substantial progress in the next few years,” Metzger says.For now, as CHIME’s commissioning phase winds down, Milutinovic’s job is to ensure that it keeps doing its job. “You want it to be boring,” he says. “It’s the weather that gives us most issues”—snow on the troughs, summer heat waves that tax the cooling system for the electronics. Then there’s the grass, a wildfire risk. Every summer, the observatory invites ranchers to graze their cattle on-site—not only to be neighborly, but also because cows emit less radio frequency interference than a lawn mower. But they can’t graze right around CHIME because they might chew on cables. So Milutinovic relies on diesel-powered mowers, which, lacking spark plugs, pose less of an interference problem.But he longs for an even better high-resolution grass-cutting tool. “We thought of having a CHIME goat.”*Correction, 15 March, 11:15 a.m.: An earlier version of this story misstated Paul Scholz’s affiliation.
