Simulations of coalescing black holes

Simulations of coalescing black holes

Agnieszka Janiuk and Szymon Charzyński

Binary black holes can be quite ubiquitous in the Universe. The massive stars are expected to form BHs at the end of their lives. We already know a few dozen of stellar mass BHs that are in X-ray binary systems, so that in case of a high mass X-ray binary, it is expected that the system evolves to form of a binary black hole. Supermassive black holes (106 - 108 MSun) are thought to exist in the centers of most galaxies. Galaxy merging process observed to be ongoing in number of cases (Volonteri et al., 2015) inevitably involves the merger of a binary black hole as the nal phase of galaxy merger. One example is the pair of merging galaxies in the cluster Abell 400, also, the kinked jet, observed in the galaxy NGC 326, suggests that the merger process might have happened there in the past.
