fast radio burst

fast radio burst (plural fast radio bursts)

1. (astronomy) A tight band of radio-frequency waves that lasts only a millisecond, which packs the energy of millions of years of Solar output.
   • 2016, Günter Sigl, Astroparticle Physics, Springer, →ISBN, page 571:

     This would confirm a cosmological origin of the fast radio burst, although this was disputed because the afterglow could also be caused by conventional AGN activity.

2. (by extension) An instance of one of the phenomena which generate such a burst.
3. (by extension) An object from which the phenomenon occurs.
