Evolution of Dense Star Clusters with Massive Black Holes

Final Activity Report Summary - EVODESC (Evolution of Dense Star Clusters with Massive Black Holes)

Galactic nuclei are among the most fascinating astronomical objects, and are a frequent target for observations. Recently, our own Galactic centre has been subject to observations in multiple wavelengths. These observations revealed the very young stars as well as the evidence for black holes about a thousand solar masses, moving around a supermassive black hole, which is about four million solar masses. The unique structure of the orbits in the vicinity of a supermassive black hole leads to novel dynamical processes that cannot be simulated by tradintional techniques.

In our project, we developed new techniques to simulate the processes that are most important for the dynamical evolutions of the young stars and the gravitational wave sources. We made many of the numerical tools that we developed freely available to the public via world wide web. These are used by our colleagues both for simulating galactic nuclei and planetary systems, which share many physical characteristics with the former.
