The 1st ever merger of black hole of different masses was observed by LIGO-LVC indicated by GW190412 signal. Who published this study?
Answer with explanationAnswer: Option B
Laser Interferometer Gravitational Wave Laboratory (LIGO) Scientific Collaboration and the Virgo Collaboration also known as LVC (LIGO Scientific Collaboration and Virgo Collaboration)discovered binary black hole (BBH) merger with different masses for the first time. This study has been published in preprint server ArXiv.This discovery took place a year after when a gravitational wave (GW) signal dubbed “GW190412”observed by the LIGO and Virgo detectors on 12 April 2019, which was actually a sign of merging of two black holes with unequal masses. This merger took place 2.4 billion light years away.
