Important points
The two objects are bound to merge in the future: the quasar is moving at a speed of only a few tens of thousands of kilometres per hour with respect to the companion galaxy and their separation is only about 22,000 light-years
HE0450-2958, which is the only one for which no sign of a host galaxy has yet been detected.
The question of which came first, the supermassive black holes that frantically devour matter or the enormous galaxies where they reside, is one of the most debated questions in astronomy.
A observation that could help resolve a long-standing mystery as to why the masses of black holes are larger in galaxies that contain more stars.

which came first do you think came first, the supermassive black holes or the galaxies where they reside. This single observation is by no means a smoking gun, though, aside from that I had learned from my text book that the black hole forms and then the galaxy's central bulge forms around it and then the galaxy forms around the central bulge. Not that the black hole forms separate form the galaxy and then merges with the galaxy later on.
