Description
Highest resolution Event Horizon Telescope (EHT) observations will probably soon
tell us more about the supermassive black hole at the Galactic Centre (Sgr A*) and the cores of active galactic nuclei (AGN).
It might also help to clarify the long-standing question whether the central massive
objects in AGN are instead close pairs of black holes. Mergers of supermassive black hole pairs would provide the strongest gravitational wave signals.
I will present examples of how we identify potential close binary black hole
candidates based on the combined analysis of high resolution radio interferometric (VLBI) observations and multi-wavelength data. I will also provide an outlook on the scientific prospects with regard to future EHT-observations of these AGN.
