Astronomers and astrophysicists expect that fast radio bursts (FRBs) happen all the time. Some estimates predict there are up to 10,000 per day. But they are not easy to detect. Telescopes with a wide field of view often don’t have good resolution. And the ones that have good resolution usually come with a much smaller field of view and might be missing them all the time.
FRBs are so short that regular follow-up observations by other radio or optical telescopes are not realistic. This could be a depressing scenario for scientists, but guess what: neutrinos might come to the rescue.
