סמינר באסטרונומיה ובאסטרופיזיקה: Dynamics & Transients Around Supermassive Black Holes

Zoom: https://tau-ac-il.zoom.us/j/87185167411?pwd=FpTUyIgXaOturzOFSetA6pPVYQilen.1

Abstract:

Most galaxies host a supermassive black hole (SMBH) at their center, surrounded by a dense cluster of stars and stellar-mass black holes. In this talk, I will discuss how two-body scattering and gravitational wave emission shape the stellar distribution around SMBHs, giving rise to a range of transients, such as tidal disruption events, X-ray quasi-periodic eruptions, and gravitational wave sources. I will focus on extreme mass-ratio inspirals — mergers of stellar-mass black holes with SMBHs - examining their formation rate and estimating the number of events that will be detectable by LISA, the upcoming space-based gravitational wave observatory.
