Abstract

GW190521 is the most massive binary black hole (BBH) merger observed to date. Due to its peculiar properties, the origin of this system is still a matter of debate: several hints may favor a dense stellar environment as a birthplace. Here, we investigate the possible formation of GW190521-like systems via three-body encounters in young massive star clusters (YSCs) by means of direct N-body simulations.
