The method, developed by researchers from the University of Cambridge, could be used to detect and measure so-called black hole superkicks, which occur when two spinning supermassive black holes collide into each other, and the recoil of the collision is so strong that the remnant of the black hole merger is bounced out of its host galaxy entirely. Their results are reported in the journal Physical Review Letters.
The collision of two black holes 1.3 billion years ago (as shown in this animation) produced gravitational waves that were detected for the first time by researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO) on September 14, 2015.
