Abstract:It is generally accepted that all massive galaxies host supermassive black holes in their center1 and that mergers of two galaxies lead to the formation of black hole binaries2. The most interesting among them comprise the mergers in their final state, i.e. with pc (3.2 light years) or sub-pc orbital separations. Binary self-lensing is a possibility to detect these systems.
Here we report the detection of a central supermassive black hole binary in the active galaxy (AGN) NGC1566 based on a microlensing outbu… Show more
