An ungrad student was making a study that would compare sources of x-rays with the positions of galaxies when she discovered something that made the community of astronomers to raise their collective eyebrows: Supermassive black holes were, apparently, expelled by the center of a galaxy!
The initial suspicion is that this event was cause by the collision of two smaller black holes.
For a previous discussion on the nature of black hole collision (and some more links about the difficulties in computing this) just visit this heated thread: Thread 117923
