Primordial Black-Hole-Based Pathways to Little Red Dots

Valerio De Luca, Loris Del Grosso, Gabriele Franciolini +4

The James Webb Space Telescope has uncovered a population of compact, high-redshift sources, the Little Red Dots (LRDs), which may host supermassive black holes (BHs) significantly…

GW231123: A Possible Primordial Black Hole Origin

Valerio De Luca, Gabriele Franciolini, Antonio Riotto

GW231123, the heaviest binary black hole merger detected by the LIGO-Virgo-KAGRA Collaboration to date, lies in the pair-instability mass gap and exhibits unusually high component…

Tidal deformability of black holes surrounded by thin accretion disks

Enrico Cannizzaro, Valerio De Luca, Paolo Pani

The tidal Love numbers of self-gravitating compact objects describe their response to external tidal perturbations, such as those from a companion in a binary system, offering valu…

Superfluid Dark Matter

Lasha Berezhiani, Giordano Cintia, Valerio De Luca +1

The superfluid dark matter model offers an elegant solution to reconcile discrepancies between the predictions of the cold dark matter paradigm and observations on galactic scales.…

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…

Flea on the elephant: Tidal Love numbers in subsolar primordial black hole searches

Valerio De Luca, Gabriele Franciolini, Antonio Riotto

Detecting subsolar objects in black hole binary mergers is considered a smoking gun signature of primordial black holes. Their supposedly vanishing tidal Love number is generically…
