If you have a question about this talk, please contact Denis.

I will discuss some recent developments in modelling multiple stellar-mass objects orbiting around a galactic centre, supermassive black hole. This includes relativistic extension of the mean motion resonance, an effect extensively studied in planetary systems, e.g. in explaining the formation of orbital structure of Jupiter’s moons and the rings in the gaps of Saturn. It turns out that this mechanism may generate locked pairs of stellar-mass black holes in AGN disks that migrate towards the supermassive black hole together. I will also show that, if there is a close third body near an extreme mass-ratio inspiral (EMRI) system, the gravitational force due to the third could generate observational signatures in the EMRI waveform through a new resonance effect.
