The rate and the origin of type Ia supernovae in radiogalaxies

Abstract

An analysis of type Ia supernova (SNIa) events in early type galaxies from Evans et al. (1989) database provides strong evidence that the rate of type Ia supernovae (SNe) in radio-loud galaxies is about 6 times higher than the rate measured in radio-quiet galaxies, i.e. SNIarate(radio − loud galaxies) = 0.47 −0.15 h 2 50 SNe per century and per 10 L ⊙ (SNU… (More)
