How do binary black holes (BBHs) merge in our Universe? In the new era of gravitational wave (GW) astrophysics with LIGO /Virgo and KAGRA , we are finally in a position to get insight into this fundamental question. I will in my talk discuss indirect observational hints of GW sources forming in stellar clusters and Active Galactic Nuclei (AGN) disks. I will further present new ideas on how to probe the origin of individually dynamically formed BBH mergers using GWs alone by the use of eccentric burst timing measurements, which is likely the only way we can probe the origin of GW sources case-by-case.

Johan Samsing is a Louis-Hansen Assistant Professor, Villum-Young Investigator and Marie Curie Fellow at the Niels Bohr International Academy in Copenhagen, Denmark. He was formerly the Einstein/Spitzer Fellow at Princeton. His research focusses on the dynamical formation of gravitational-wave sources, specifically binary black hole mergers, in environments like globular clusters and active galactic nuclei. For his most recent publication on the formation of eccentric mergers in AGN , see Samsing et al. 2022.
