Static response and Love numbers of Schwarzschild black holes
Lam Hui, Austin Joyce, Riccardo Penco +2
We derive the quadratic action for the physical degrees of freedom of massless spin-0, spin-1, and spin-2 perturbations on a Schwarzschild--(A)dS background in arbitrary dimensions…
An Introduction to Effective Field Theories
Riccardo Penco
These notes are an overview of effective field theory (EFT) methods. I discuss toy model EFTs, chiral perturbation theory, Fermi liquid theory, and non-relativistic QED, and use th…
Extreme Mass Ratio Inspirals with Scalar Hair
Adrien Kuntz, Riccardo Penco, Federico Piazza
Stellar mass objects orbiting around supermassive black holes are primary targets for future gravitational wave detectors like LISA. However, in theories beyond general relativity,…
Baryon-Interacting Dark Matter: heating dark matter and the emergence of galaxy scaling relations
Benoit Famaey, Justin Khoury, Riccardo Penco +1
The empirical scaling relations observed in disk galaxies remain challenging for models of galaxy formation. The most striking among these is the Mass Discrepancy-Acceleration Rela…
