Summary
An analysis of type Ia supernova (SNIa) events in early type galaxies from the Cappellaro et al. [6] database provides strong evidence that the rate of type Ia supernovae (SNe) in radio-loud galaxies is about 4 times higher than the rate measured in radio-quiet galaxies, i.e. SNIa-rate(radio-loud)=0.41−0.14/+0.13 h75/2 SNe per century and per 1010L⊙/B (SNU) as compared to SNIa-rate(radio-quiet)= 0.11 ± 0.03 h75/2 SNU. The exact value of the enhancement is still rather uncertain, but is likely to be in the range ≈2 − 7. We discuss the possible causes of this result and we conclude that the enhancement of the SNIa explosion rate in radio-loud galaxies has the same common origin as their being strong radio sources, but that there is no causality link between the two phenomena. We argue that repeated episodes of interaction and/or mergers of early type galaxies with dwarf companions are responsible for inducing both strong radio activity in ≈ 14% of early type galaxies, and the ≈ 1 Gyr old stellar population needed to supply an adequate number SNIa progenitors.
