New Haven, Conn. – A slow dance lasting up to 10 million years between a super-massive black hole and a smaller one culminates in a violent outflow of energy, possibly powering the bright light known as a quasar, a Yale researcher and collaborator have found. "Ours is the first detailed calculations of how the merger of these two super-massive black holes proceeds," said Priyamvada Natarajan, assistant professor of astronomy at Yale. "This second phase, the merger, takes a few million years. And then there is a huge outflow of gas, and the quasar shines very brightly. It’s a violent, very high energy event."
