Formation of black holes in the pair-instability mass gap: Hydrodynamical simulations of a head-on massive star collision
Alessandro Ballone, Guglielmo Costa, Michela Mapelli +3
The detection of the binary black hole merger GW190521, with primary black hole mass , proved the existence of black holes in the theoretically pr…
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…
Dynamics of binary black holes in young star clusters: the impact of cluster mass and long-term evolution
Stefano Torniamenti, Sara Rastello, Michela Mapelli +3
Dynamical interactions in dense star clusters are considered one of the most effective formation channels of binary black holes (BBHs). Here, we present direct body simulations…
