Galaxies with two black holes

    Apparently rare - only 12 galaxies are known to exist with two black holes in their midst, according to Dr. Julie Comerford.

    Comerford reported a recent observation of a double black hole galaxy at the American Astronomical Society's annual meeting in Kissimmee, Florida. One of the BHs is described as skinny.

    Galaxy mergers should complete (as far as their stars are concerned) much sooner than their SMBHs finally merge. So there should be lots of double and even triple-SMBH galaxies out there. I guess we know only a few of them because detecting multiple SMBHs in a galaxy core requires dedicated observations tailored to this task.

    So, the question is, have we observed any bizarre consequences attributable to dual SMBH in the same galaxy? I would say not, and would guess the consequences are typically trivial.
