Description
Tidal Love numbers describe the conservative response of compact objects to external tidal perturbations. Remarkably, within General Relativity, they are found to vanish exactly for black holes in vacuum. We begin by revisiting this vanishing property from a symmetry-based perspective. We then explore how this feature is modified when black holes are embedded in external environments, assessing the prospects for detecting environmental-induced tidal effects with future gravitational wave observations. Finally, we quantify the systematic biases introduced when tidally deformed binaries in environments are incorrectly modelled as isolated systems.
