If you have a question about this talk, please contact Silvia Toonen. PhD meet & greet at 12.30 Over the past five years, several merging compact object binary systems have been detected through gravitational waves by the LIGO /Virgo detectors. While these observations provide a new window to observe the universe, they also raise important questions about the astrophysical origin and formation of these elusive binary systems. In this talk, I will discuss the various processes by which gravitational wave sources can form in dense stellar clusters. The retention and long-term evolution of compact objects in stellar clusters depends on a variety of physical processes that are not fully understood. I will give an overview of these processes and explain how they shape the properties and merger rates of binary black holes that originate in dense environments. Additionally, it has also been suggested that massive and dense star clusters could be potential sites for forming black holes with masses between ~ 100 to 10,000 solar masses. I will talk about the key processes and caveats involved in the formation, retention and growth of these intermediate-mass black holes in the densest star clusters. I will also discuss how these clusters that host intermediate-mass black holes can end up in the galactic centre where they may play a role in seeding the formation of super-massive black holes.
