SummaryBinary supermassive black holes are important for our understanding of the galaxies’ formation and evolution. Coalescing binaries are among the strongest emitters of gravitational waves in the universe. With high-resolution radio observations close pairs of massive black holes can be resolved spatially, providing a direct means of detection. The closest binaries can no longer be spatially resolved, and other methods of detection are in use. Recently, first hints for the influence of a supermassive binary black hole on the lightcurve of an X-ray outburst from a non-active galaxy were found.
