The galaxy NGC 6240 contains three supermassive black holes

An article published in the journal “Astronomy & Astrophysics” reports a study on the galaxy NGC 6240 with evidence that it contains three supermassive black holes. A team of researchers led by Professor Wolfram Kollatschny of the University of Göttingen used the MUSE instrument mounted on ESO’s VLT in Chile together with data from previous studies to obtain the high-precision observations needed to verify that within NGC 6240 there were not two supermassive black holes as it seemed from previous studies but three. This indicates that the current merger is involving three galaxies.
