Indian astrophysicists spot rare merger of three jumbo black holes
A rare merging of three supermassive black holes has been spotted by a team of astrophysicists in India. They were observing the merging of two galaxies named NGC7733 and NGC 7734 in our celestial neighbourhood when they detected unusual emissions from the centre of the latter and a curious movement of a large bright clump within it, having a different velocity than that of NGC7733. Inferring that this was a separate galaxy, the scientists named it NGC7733N. There are supermassive blackholes, which are several million solar masses in size, at the centres of galaxies, and these are known as Active Galactic Nuclei. Since they “accrete“ matter, they often have a glow around them which can be observed using light spectroscopy.
