The Merger of Two Black Holes with Unequal Masses
https://www.ligo.caltech.edu/news/ligo20200420 In a first, a group of space experts has identified gravitational waves emerging from the merger of two Binary Black Holes (BBH) with significantly unequal masses. GW190412 is the first observation of a binary black hole merger where the two black holes have distinctly different masses of around eight and 30 times that of our Sun. This is the first binary black-hole system observed that have a significant difference between the masses. This big mass difference means astronomers can accurately measure several properties of the system, such as its distance to us, the angle we look at it, and how fast the heavy black hole spins around its axis. GW190412 was first observed by both LIGO detector and the Virgo finder on the 12th of April 2019, early during the detector’s third observation run O3. Examinations uncover that the merger occurred at a distance of 1.9 to 2.9 billion light-years from Earth. The new unequal mass system
