Ways of Probing the Assembly Mechanism of Individual Black Hole Binary Mergers

If you have a question about this talk, please contact Mor Rozner .

I will illustrate how different binary black hole (BBH) merger formation channels give rise to phase shifts, or modulations, in the GW signal that can be used to infer the origin of individual BBH mergers. I will in particular describe the case of GW phase shifts arising from chaotic triple BH scatterings that are known to take place in stellar clusters. New ideas on GW phase shifts in strong lensing events will also be presented. Modeling, quantifying and looking for GW modulations will start to play a key-role in the coming years when the GW sensitivity goes up and might be the only way of determining the origin of GW events case-by-case.
