WebFeb 4, 2024 · We study the gravitational-wave (GW) signatures of clouds of ultralight bosons around black holes (BHs) in binary inspirals. 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. 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. WebJan 26, 2024 · Black holes typically rotate (spin) because they form from dying stars that spin themselves, Varma said. When two such black holes orbit each other in a binary, their spins interact with the orbit. Binary black holes lose energy to gravitational waves, causing the black holes to move toward each other and eventually merge, Varma said. greyton news
