An image of the galaxy SDSS J1126+2944 taken with the Hubble Space Telescope and the Chandra X-ray Observatory. The X-ray observations, shown in purple, reveal the locations of two black holes, which were brought together by a merger of two galaxies. The arrow points to the black hole that has relatively few stars surrounding it, a possible indication that is an "intermediate" mass black hole.
One of them shows indications that it could be a rare "intermediate" mass black hole. CU assistant professor Julie Comerford spoke with Colorado Matters host Nathan Heffel.
