Abstract

In this talk, we discuss the exciting possibilities of exploring strong gravity with future GW observations. The properties of Black-Holes (BH) and exotic compact objects (ECOs) immersed in a tidal environment are discussed. In particular, we focus on the BH reaction and its induced quadrupole moment to an external tidal field. The no-Love number theorem for GR BHs is thoroughly reviewed and alternative explanations are suggested. Here, I'll present for the first time how simple quantum mechanical arguments support the existence of the Love number in quantum black-holes, moreover I'll show how the detection of these quantum induced effects is possible with future precision gravitational wave measurement.
