Imprints of recoiling massive black holes on the hot gas of early type galaxies
... Anisotropic gravitational radiation from a coalescing black hole (BH) binary is known to impart recoil velocities of up to ∼1000 km s − 1 to the remnant BH. In this context, we study the motion of a recoiling BH ...
