These clouds, which are formed via superradiance instabilities for rapidly rotating BHs, produce distinct effects in the population of BH masses and spins, and a continuous monochromatic GW signal.

Assessing the ubiquity of massive black holes in earlier times [1], [2], a large number of massive black hole binaries (MBHBs) are expected to have formed over the course of cosmic history [3].The coalescences of MBHBs with total masses of 10 5 M ⊙ − 10 8 M ⊙ due to galaxy mergers provide a primary source of low … WebAug 20, 2010 · Here, we examined the interaction of a binary black hole system with an environment filled with a conducting plasma and a magnetic field as the black holes orbit around each other, ultimately colliding and merging. Such a system is expected as a natural consequence of galaxy mergers.
