Black Holes and Neutron Stars in Numerical General Relativity — •Bernd Bruegmann — University of Jena, Germany

Black holes and neutron stars are paradigms of extreme gravity described by Einstein's theory of general relativity. This talk reviews recent progress in numerical relativity that allows the simulation of the general relativistic two body problem for black holes and neutron stars. A key result is how such binaries generate gravitational waves that provide information about astrophysical phenomena like collisions and mergers at the endpoint of the gravitational inspiral. As a recent development we discuss simulations of binary neutron stars with realistic spin, which go beyond the conventional approximation of corotating or irrotational neutron stars.
