Constraining the Initial Primordial Black Hole Clustering with CMB-distortion
V. De Luca, G. Franciolini, A. Riotto
The merger rate of primordial black holes depends on their initial clustering. In the absence of primordial non-Gaussianity correlating short and large-scales, primordial black hol…
Standard Model Baryon Number Violation Seeded by Black Holes
V. De Luca, G. Franciolini, A. Kehagias +1
We show that black holes with a Schwarzschild radius of the order of the electroweak scale may act as seeds for the baryon number violation within the Standard model via sphaleron…
Bayesian Evidence for Both Astrophysical and Primordial Black Holes: Mapping the GWTC-2 Catalog to Third-Generation Detectors
V. De Luca, G. Franciolini, P. Pani +1
We perform a hierarchical Bayesian analysis of the GWTC-2 catalog to investigate the mixed scenario in which the merger events are explained by black holes of both astrophysical an…
Constraining graviton non-Gaussianity through the CMB bispectra
Valerio De Luca, Gabriele Franciolini, Alex Kehagias +2
Tensor non-Gaussianities are a key ingredient to test the symmetries and the presence of higher spin fields during the inflationary epoch. Indeed, the shape of the three point corr…
Gravitational Wave Anisotropies from Primordial Black Holes
N. Bartolo, D. Bertacca, V. De Luca +6
An observable stochastic background of gravitational waves is generated whenever primordial black holes are created in the early universe thanks to a small-scale enhancement of the…
Electromagnetic probes of primordial black holes as dark matter
Y. Ali-Haimoud, S. Clesse, J. Garcia-Bellido +91
The LIGO discoveries have rekindled suggestions that primordial black holes (BHs) may constitute part to all of the dark matter (DM) in the Universe. Such suggestions came from 1)…
Testing Primordial Black Holes as Dark Matter through LISA
N. Bartolo, V. De Luca, G. Franciolini +3
The idea that primordial black holes (PBHs) can comprise most of the dark matter of the universe has recently reacquired a lot of momentum. Observational constraints, however, rule…
