Escaping the Pair-Instability Mass Gap with the Help of Dark Matter

Abstract

Black Holes are not expected to form in the mass range of 60 M⊙ to 130 M⊙ because of the Pair-Instability Supernova (PISN). However, the recent observational evidence of GW190521 does not comply with the existing theory. Here, we have looked into the effects of Dark Matter (DM) in the progenitors of PISN in terms of luminosity, lifetime and temperature and have shown that in the presence of DM particles, the progenitors can overcome the PISN stage to collapse into a black hole (BH) as a remnant.
