Dynamical Love numbers of black holes: Theory and gravitational waveforms
Sumanta Chakraborty, Valerio De Luca, Leonardo Gualtieri +1
In General Relativity, the static tidal Love numbers of black holes vanish identically. Whether this remains true for time-dependent tidal fields -- i.e., in the case of dynamical…
Primordial black hole ringdown: The irreducible stochastic gravitational wave background
Valerio De Luca, Antonio J. Iovino, Antonio Riotto
Independently from the formation mechanism of primordial black holes in the early Universe, their generation is accompanied by a ringdown phase during which they relax to a station…
Systematic biases from ignoring environmental tidal effects in gravitational wave observations
Valerio De Luca, Loris Del Grosso, Francesco Iacovelli +2
Binary black hole systems are typically assumed to evolve in vacuum. However, the environment surrounding the binary components can influence their properties, such as their tidal…
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…
Tidal deformability of dressed black holes and tests of ultralight bosons in extended mass ranges
V. De Luca, P. Pani
The deformability of a compact object under the presence of a tidal perturbation is encoded in the tidal Love numbers (TLNs), which vanish for isolated black holes in vacuum. We sh…
The Astro-Primordial Black Hole Merger Rates: a Reappraisal
K. Kritos, V. De Luca, G. Franciolini +2
Mainly motivated by the recent GW190521 mass gap event which we take as a benchmark point, we critically assess if binaries made of a primordial black hole and a black hole of astr…
Constraining the primordial black hole scenario with Bayesian inference and machine learning: the GWTC-2 gravitational wave catalog
Kaze W. K. Wong, Gabriele Franciolini, Valerio De Luca +4
Primordial black holes (PBHs) might be formed in the early Universe and could comprise at least a fraction of the dark matter. Using the recently released GWTC-2 dataset from the t…
