Project information
Supermassive black holes are located in most if not all centres of galaxies, including our own. Their growth due to interaction with and accretion of surrounding gas and stars is one of the most interesting and important fields in astrophysics nowadays. New space and ground based telescopes of present (Hubble Space Telescope, VLT, Chandra, XMM Newton) and future generations (Next Generation Space Telescope) provide a large amount of new high-resolution data on morphology and kinematics of stellar and gaseous systems near black holes. Since the underlying equations are very complex, theory consists of computer simulations in which the evolution of stars (gravitating mass points) with a central potential (black hole) and a gaseous disk is followed by direct modelling of stellar orbits. The project examines a special topic in this area, namely the interplay between stellar dynamical two-body relaxation and star-gas interactions due to a central accretion disk. The proposed computing facility in Almaty is supposed to be included in the world wide MODEST network and will take part in the forefront of a newly planned grid network of such facilities.
