Galaxies may have spit out monster black hole
Astronomy Thursday, November 17, 2005 . This is a SciScoop post by worldscience
A collision between two galaxies may have led them to spit out a colossal black hole that’s still soaring through space, some astronomers have calculated.
If correct, the proposal would be the first evidence of a possibility astrophysicists have theorized for years: a black hole’s expulsion from a galaxy.
Indirectly, it could also shed light on how some black holes became as big as they are–a longstanding puzzle that’s also entangled with the question of how galaxies formed.
A team of researchers describe the results in a paper to appear in an upcoming issue of the
Monthly Notices of the Royal Astronomical
Society, a research journal.
They claim an enigmatic object known as HE0450-2958, estimated to weigh as much as 400 million suns or more, may be the expelled black hole.

Another paper submitted to Monthly Notices of the Royal Astronomical Society by David Merritt et al claims that the quasar is a garden-variety narrow-line Seyfert 1 with the host galaxy simply too faint to be seen. So sayeth a recent article at Newscientist . The original discoverer said it would have taken the collision of three galaxies to eject such a large black hole, so I find find the narrow-line Seyfert 1 argument more compelling.
