Dynamical Formation of Black Hole Binaries
The advanced detectors of gravitational waves detected two black hole binary mergers and one candidate. Such binaries are either formed by evolution of binary systems composed of two massive stars of through dynamical processes in dense stellar systems. The speaker will focus on the dynamical scenarios originating from globular clusters. The galactic nuclei star clusters (NC) could also provide suitable environment for the dynamical binary formation, but they are likely to be much less efficient. The spin directions of individual black holes would be random for dynamical binaries. Also we expect the mass ratios of two black holes in binaries would be close to 1. Binaries composed of a black hole and a neutron star will be very rare among dynamical binaries.
