On the Origins of “Hostless” Supernovae: Testing the Faint-end Galaxy Luminosity Function and Supernova Progenitors with Events in Dwarf Galaxies

On the Origins of “Hostless” Supernovae: Testing the Faint-end Galaxy Luminosity Function and Supernova Progenitors with Events in Dwarf Galaxies

We present arguments on the likely origins of supernovae without associated host galaxies from open field, nonclustered environments. We show why it is unlikely these “hostless” supernovae stem from escaped hypervelocity stars in any appreciable numbers, or the extreme outer halos of large galaxies,...
