Zooming-in on the sources of fast radio transients

, 2022
Since the 1960s, Galactic neutron stars have been known to emit short duration radio transients. More recently, a population of higher luminosity short-duration radio transients originating from extragalactic distances were discovered. The nature of these fast radio bursts (FRBs) still remains a mystery, but it is clear that they reflect an extreme ...
