25. Fundamental Physics and Gravitational Waves

Riccardo Sturani (IFT-UNESP/ICTP-SAIFR)

The detections of gravitational waves emitted by compact binary coalescences gave rise to the new science of Gravitational Wave Astronomy, which opened up new possibilities for scientific investigation also in cosmology and fundamental physics. In this presentation I will give an overview of the observational results and some hints to the impact they had, are having and will have on our...

26. Absorptive Effects and Classical Black Hole Scattering

Callum Jones

I will describe an approach to incorporating absorption effects into the post-Minkowskian effective description of two-body classical gravitational scattering. By coupling the usual point-particle effective description to an invisible sector of gapless internal degrees-of-freedom, the leading-order absorptive effects are encoded in the low-energy expansion of a spectral density function; for...
