From the current (1/20/07) issue of Science News:

“At the Seattle meeting, theorist Fred Rasio of Northwestern University in Evanston, Ill., described new simulations of the interactions of three closely spaced supermassive black holes. His team finds that when a third black hole meets up with two already orbiting each other, one of the trio tends to get kicked out of the system while the other two orbit more closely, hastening their eventual merger.”
