Outline of Research at the Start

This project aims at characterizing the properties of gravitational waves (GWs) originating from compact object binaries residing in galactic nuclei. The astrophysical origin of gravitational wave sources is still unknown. Nuclear star clusters around a central massive black hole (BH) are expected to be abundant in stellar BH remnants and BH binaries. In this project I will develop an innovative hybrid Monte-Carlo/N-body model able to follow the evolution of binaries in galactic nuclei in order to provide a complete understanding of the evolution of GW progenitors in galactic nuclei.
