Astronomers May Be Closing in on Source of Mysterious Fast Radio Bursts (theguardian.com)

Astronomers appear to be closing in on the source of enigmatic radio pulses emanating from space that have become the subject of intense scientific speculation. From a new report: Previous candidates for the origin of the fleeting blasts of radiation -- known as fast radio bursts, or FRBs -- have included exploding stars, the reverberations of weird objects called cosmic strings or even distant beacons from interstellar alien spaceships. Now, new observations provide backing for a scenario involving a rapidly rotating neutron star cocooned by an ultra-powerful magnetic field. The explanation is more orthodox than some of the alternatives offered, but could point astronomers towards some of the most extreme magnetic environments in the known universe.

"Our preferred model is that they are coming from a neutron star ... that could be just 10 or 20 years old in an extreme magnetic environment," said Jason Hessels, a co-author of the new paper and astronomer at the Netherlands Institute for Radio Astronomy in the Dutch town of Dwingeloo. Fast radio bursts have perplexed astronomers ever since the signals were discovered in 2007 in earlier observation data from the Parkes radio telescope in Australia.
About 30 of these objects have been discovered deep in space since the first was detected, all but one burping out a cataclysmic radio pulse exactly once and then disappearing into the night. Only one burster, known as FRB121102, after the date it was discovered (Nov. 2, 2012), has repeated itself, hundreds of times now.

      And they were also "perytons" rather than FRBs.

      Identifying the source of perytons at the Parkes radio telescope
      "Perytons" are millisecond-duration transients of terrestrial origin, whose frequency-swept emission mimics the dispersion of an astrophysical pulse that has propagated through tenuous cold plasma. In fact, their similarity to FRB 010724 had previously cast a shadow over the interpretation of "fast radio bursts," which otherwise appear to be of extragalactic origin. Until now, the physical origin of the dispersion-mimicking perytons had remained a mystery. We have identified strong out-of-band emission at 2.3--2.5 GHz associated with several peryton events. Subsequent tests revealed that a peryton can be generated at 1.4 GHz when a microwave oven door is opened prematurely and the telescope is at an appropriate relative angle. Radio emission escaping from microwave ovens during the magnetron shut-down phase neatly explain all of the observed properties of the peryton signals. Now that the peryton source has been identified, we furthermore demonstrate that the microwaves on site could not have caused FRB 010724. This and other distinct observational differences show that FRBs are excellent candidates for genuine extragalactic transients.

      Which if you stop and think about it, isn't that surprising.

      The universe is vast. Pretty much anything we can think of in terms of the lifecycle of stars and galaxies has probably happened somewhere, and likely many many things we can't think of or haven't yet figured out. This is over a span of billions of years.

      With billions and billions of galaxies, each with billions and billions of stars, and spanning billions of years, that occasionally one of these suckers points at is isn't that surprising. It's almost inevitable I should think.

      It's like spotting exoplanets based on orbital transits ... they have to be aligned just so in order that we see them from here. But we've seen tons of them, telling us they're pretty darned common throughout the universe. And we can only hope to see stuff in our 'nearby' neighborhood.

      So, yeah, we've found a handful of these things ... which means in the short period of time we've been listening, a small handful of these have by fluke been aimed well enough for us to see them.

      Which probably also implies that in the billions of years since some of these have happened, there's been tons of the damned things which either we missed because we weren't listening, or because they weren't pointed straight at us.

      To quote the movie Armadeggon ... begging your pardon sir, but it's a big ass sky.

      The universe isn't lacking in high energy events which are big and scary .. over the long run, the universe is a pretty hostile place. Stars and galaxies don't survive in the long enough time scales. We're just specs on an insignificant little piece of it trying to understand the stuff we can see, when the overwhelming amount of it is stuff we can't.

      The universe is 'awesome' in the most literal and original sense of the word, because it operates on scales and timelines our little monkey brains can't every truly grasp. Hell, I'm sure the people who study it periodically step away from the calculations and just sorta go "damn but that's big" ... it's one thing to be able to calculate eleventy zillion, it's another to truly take it in and grasp it. After that, it's just math with a lot of zeroes, but is otherwise largely an abstraction.

      For a few of these now and then to be direct hits? That's pretty much inevitable. That we can figure out what we think they are from here? That's pretty much incredible.
