The Role of Black Holes in Globular Cluster Dynamics
Kyle Kremer (Northwestern)
Over the past few years, the groundbreaking detections of gravitational-wave (GW) signals from merging binary black holes (BHs) and neutron stars (NSs) by LIGO/Virgo have opened a new window to the cosmos. One key question regarding these GW sources concerns the nature of their origin. Dynamical formation in dense stellar environments like globular clusters (GCs) has emerged as an important formation channel, corroborated by recent numerical simulations and observational indications suggesting that GCs may contain dynamically significant populations of stellar-mass BHs throughout their lifetimes. In this talk, I will examine ways BH populations influence the dynamical evolution and observable properties of GCs and discuss the dynamical formation of merging BH binaries that may be detectable by LIGO/Virgo and LISA and various other stellar exotica including tidal disruption events and low-mass X-ray binaries.
