12. Environmental effects and matter systematics for low-frequency gravitational wave astronomy

Enrico Barausse (SISSA)

Despite the groundbreaking discoveries of the LIGO-Virgo-KAGRA collaboration, the full frequency spectrum of the gravitational wave sky is still largely unknown. The Einstein Telescope will push observations on Earth down to the seismic noise, while LISA will
open a window on the mHz gravitational wave band from space. At the same time, pulsar timing arrays, which have just detected a...

13. Detecting disk-induced environmental effects

Gravitational-wave observations of extreme mass ratio inspirals (EMRIs) hold incredible potential to probe gravity, astrophysical and exotic environments. One of the main effects of astrophysical environments is the torque exerted by gas disks of active galactic nuclei, which force the EMRI to “migrate” (mostly) inward like a planet. We present a Bayesian model-independent framework to detect...

14. Dynamical tidal resonances in EMRIs

Beatrice Bonga (Radboud University)

9/21/23, 10:00 AM

Resonances are ubiquitous in nature. In this talk, I will focus on resonances due to the interaction of two stellar-mass black holes orbiting a central massive black hole. Such tidal resonances will generically occur for Extreme Mass Ratio Inspirals (EMRIs), if nearby compact objects exist. By probing their influence on the EMRI waveform, we can in principle extract information about the...
