First fast-radio-burst source ID’d

[smp]

From Ars Technica:
"Today, researchers are announcing they've solved one of the questions that's been nagging them over the past decade: what exactly produces the weird phenomena known as fast radio bursts (FRBs)? As their name implies, FRBs involve a sudden blast of radio-frequency radiation that lasts just a few microseconds. We didn't even know that FRBs existed until 2007 but have since cataloged hundreds of them; some come from sources that repeatedly emit them, while others seem to burst once and go silent.

Obviously, you can produce this sort of sudden surge of energy by destroying something. But the existence of repeating sources suggests that at least some of them are produced by an object that survives the event. That's led to a focus on compact objects, like neutron stars and black holes, with a class of neutron stars called magnetars being viewed very suspiciously."
