Resonances in black hole spacetimes

Nov. 04 - 14:30 - 2021

Speaker: Béatrice Bonga (Nijmegen U., IMAPP)

Title: Resonances in black hole spacetimes


Resonances are ubiquitous in nature. In this talk, I will focus on resonances due to the interaction of
two black holes orbiting a central massive black hole. Such tidal resonances will generically occur for
EMRIs if nearby compact objects exist. By probing their influence on the phase of the EMRI waveform,
we can in principle extract information about the environmental tidal field of the EMRI system, albeit
at the cost of a more complicated EMRI waveform model. I will also describe mean motion resonances,
which are a mechanism that can create the necessary conditions for tidal resonance to occur.
