Seminar by Lorenzo Kuchker

Lorenzo Kuchker (ULB) will give the following seminar in the room 0A11 of the building Pentagone:

Waveforms from inspiral, transition and plunge in compact binaries

Within general relativity, the planar motion of a stellar-mass compact object around a supermassive black hole admits a quasi-circular inspiral motion followed by a transition across the innermost stable circular orbit (ISCO) and a final plunge behind the event horizon. I will present the modelling of the motion in these three regions using gravitational self-force theory and compare the waveforms generated in this framework with numerical relativity simulations.
