Speaker
Description
Star clusters are the dynamical formation channel for binary black holes (BBHs). In these dense systems, BBH mergers are driven by gravitational wave emission and binary-single encounters with other objects in the environment. The talk will focus on the gravitational wave (GW) signals generated by close encounters between a BBH and a third black hole, highlighting the various outcomes that can arise from these interactions. To estimate the GW spectrum of these signals, numerical simulations were performed using the N-body code ARWV (Chassonnery et al. 2019; Chassonnery & Capuzzo-Dolcetta 2021), with stellar mass black holes serving as input masses. The talk will also consider the potential for these burst signals to fall within the sensitivity band of current and future ground-based detectors, depending on the parameters involved.
