Abstract

Numerical modelling of dense stellar systems including black holes and compact stellar objects (neutron stars, white dwarfs), where the mass of the black holes ranges from stellar masses (end products of stellar evolution) through intermediate (103 to 104 solar masses) in star clusters up to the very end of the cosmological black hole mass function (1010 solar masses) in centres of galaxies. The relativistic (Post-Newtonian) dynamics of these objects will be formulated and numerically followed to predict gravitational waves for ground and space based GW observatories from these astrophysical objects.
