Description
Non-merging ringdown radiations have recently been discovered when two black holes closely encounter and fly-by away afterward. We present some features of such radiations for a wider space of the impact parameter and initial velocity characterizing hyperbolic encounters. Different patterns of gravitational radiations from the merging ones are also presented, focusing on the beaming effect due to the fast motions of constitute black holes.
