radio supernova

(RSN)
(supernova that includes a detectable radio emission)

A radio supernova (RSN) is a supernova for which a radio signal has been detected. The term likely is used for supernovae in which radio has been detected early on when the light curve is evident: radio is not uncommon later from supernova remnants. The early radio signal is of interest for revealing the mechanisms and evaluating theories regarding them. Such core collapse supernovae have been observed for some time, the radio emission presumed to be synchrotron radiation from ejecta interaction with the surrounding interstellar medium (ISM). Type Ia supernovae have been theorized to produce radio as well, and the first such detection was of a 2020 supernova (SN 2020eyj).
