Abstract:
About 90 gravitational wave (GW) events have been reported to date from mergers between stellar-mass black holes (BHs). While the astrophysical origin of these GW events is actively debated, the disks of active galactic nuclei (AGN) have been identified as a particularly promising environment for producing BH mergers. Given the uncertainties of these processes, it is of significant interest to identify their signatures using GWs and/or electromagnetic observations. In this talk, I will discuss the properties that can be used to constrain this channel and differentiate it from others, reflecting the properties of these mergers as predicted through semi-analytical models. Additionally, I will predict the properties of potential electromagnetic counterparts associated with BH mergers in AGN disks, and apply this model to possible counterparts reported so far.
