Formation of black holes in the pair-instability mass gap: evolution of a post-collision star
Guglielmo Costa, Alessandro Ballone, Michela Mapelli +1
The detection of GW190521 by the LIGO-Virgo collaboration has revealed the existence of black holes (BHs) in the pair-instability (PI) mass gap. Here, we investigate the formation…
