The accretion, emission, mass and spin evolution of primordial black holes
Valerio De Luca, Nicola Bellomo
Throughout the cosmic history, primordial black holes may experience an efficient phase of baryonic mass accretion from the surrounding medium. While the realm of accretion physics…
Dynamical friction in dark matter superfluids: The evolution of black hole binaries
Lasha Berezhiani, Giordano Cintia, Valerio De Luca +1
The theory of superfluid dark matter is characterized by self-interacting sub-eV particles that thermalize and condense to form a superfluid core in galaxies. Massive black holes a…
Primordial black holes and their gravitational-wave signatures
Eleni Bagui, Sebastien Clesse, Valerio De Luca +17
In the recent years, primordial black holes (PBHs) have emerged as one of the most interesting and hotly debated topics in cosmology. Among other possibilities, PBHs could explain…
How well do we know the primordial black hole abundance? The crucial role of nonlinearities when approaching the horizon
Valerio De Luca, Alex Kehagias, Antonio Riotto
We discuss the non-linear corrections entering in the calculation of the primordial black hole abundance from the non-linear radiation transfer function and the determination of th…
Non-linearities in the tidal Love numbers of black holes
Valerio De Luca, Justin Khoury, Sam S. C. Wong
Tidal Love numbers describe the linear response of a compact object under the presence of external tidal perturbations, and they are found to vanish exactly for black holes within…
Superfluid Dark Matter around Black Holes
Valerio De Luca, Justin Khoury
Superfluid dark matter, consisting of self-interacting light particles that thermalize and condense to form a superfluid in galaxies, provides a novel theory that matches the succe…
