Kicking Time Back in Black Hole Mergers: Ancestral Masses, Spins, Birth Recoils, and Hierarchical-formation Viability of GW190521
A pair-instability supernova (PISN) prevents black hole (BH) formation from stellar collapse within the approximate mass range M ∈ [65, 130] M _⊙ . However, such BHs may form hierarchically through merging ancestral BHs, whose properties determine those of the “child” one: mass, spin, and recoil vel...
