"Tidal Love numbers: from black holes to exotic physics"


Valerio De Luca , University of Pennsylvania
[Host: Kent Yagi]
ABSTRACT:

Tidal Love numbers describe the linear response of compact objects to external tidal perturbations, and they are found to vanish exactly for black holes within General Relativity. We first discuss the robustness of this property when non-linearities in the theory are taken into account, and then investigate the scenario of black holes dressed with an ultralight scalar field, addressing their detectability at future gravitational wave experiments. Finally, we discuss the tidal deformability of more exotic compact objects, showing the relevance of universality relations as a way to distinguish between them.
