The GW190412 merger revealed a black-hole recoil moving faster than 50 km/s. Gravitational waves allowed its 3D motion to be reconstructed. A research group led by the Instituto Galego de Física de Altas Enerxías (IGFAE) at the University of Santiago de Compostela (Spain) has, for the first time, determined both the speed and direction of […]



Summary

The GW190412 black hole merger exhibited a recoil velocity exceeding 50 km/s, detectable through its gravitational waves. A team at the Instituto Galego de Física de Altas Enerxías (IGFAE) in Spain successfully reconstructed the 3D motion of this recoiling black hole. This marks the first instance where both the speed and direction of such a recoil have been determined, offering new insights into the dynamics of black hole mergers and their gravitational wave signatures. The findings advance our understanding of these extreme astrophysical events.
