Hidden symmetries for tidal Love numbers: Generalities and applications to analog black holes
Valerio De Luca, Brandon Khek, Justin Khoury +1
Tidal Love numbers characterize the conservative, static response of compact objects to external tidal fields. Remarkably, these quantities vanish identically for asymptotically fl…
Scattering perspective on gravitational lensing
Mariana Carrillo Gonzalez, Valerio De Luca, Alice Garoffolo +2
Gravitational waves propagating across gravitational potentials undergo lensing effects that, in the wave-optics regime, manifest as frequency-dependent amplitude and phase modulat…
Gravitational memory and soft theorems: The local perspective
Valerio De Luca, Justin Khoury, Sam S. C. Wong
In general relativity, gravitational memory describes the lasting change in the separation and relative velocity of freely falling detectors after the passage of gravitational wave…
Gravitational memory and Ward identities in the local detector frame
Valerio De Luca, Justin Khoury, Sam S. C. Wong
Gravitational memory, which describes the permanent shift in the strain after the passage of gravitational waves, is directly related to Weinberg's soft graviton theorems and the B…
Tidal Love numbers of analogue black holes
Valerio De Luca, Brandon Khek, Justin Khoury +1
Tidal Love numbers quantify the conservative static response of compact objects to external tidal fields, and are found to vanish exactly for asymptotically flat black holes in fou…
