14. Beyond general relativity: gravitational waves in non-minimally coupled theories

Tucker Manton (HIAS-UCAS)

Non-minimal matter-curvature couplings arise in many different contexts, and modify solutions of general relativity. If dark matter (DM) experiences non-minimal couplings, the imprint can be see in gravitational waves (GWs) emitted from binary black hole mergers, where DM densities are expected to be large. In this talk, we explore effects of various non-minimal couplings on GWs by working...

17. Scalar wave emission from particles radially infalling in a Schwarzschild black hole

Giorgio Di Russo (Hangzhou Institute for Advanced Study)

I present an analytical computation of the energy emitted by a scalar particle radially infalling into a Schwarzschild black hole spacetime within the framework of the gravitational self-force. The results are expressed in Post-Newtonian expanded form, as is customary.

5. Vanishing nonlinear black hole Love numbers in GR

Sam Wong (CityU HK)

Black hole Love numbers measure how a black hole deforms under external tidal fields, providing a window into the structure of spacetime, the dynamics of black holes, and the physics of gravitational waves. While linear analyses already suggest their vanishing, the role of non-linear effects has remained an open question. In this talk, I will explore the non-linear regime, presenting recent...
