Hierarchical mergers of stellar-mass black holes and their gravitational-wave signatures
D Gerosa, M Fishbach - Nature Astronomy, 2021 - nature.com
While most of the compact-binary mergers detected by LIGO and Virgo are expected to
consist of first-generation black holes formed from the collapse of stars, others might instead …

Modeling dense star clusters in the milky way and beyond with the CMC cluster catalog
We present a set of 148 independent N-body simulations of globular clusters (GCs)
computed using the code CMC (Cluster Monte Carlo). At an age of∼ 10–13 Gyr, the …
