Pulsar timing array sensitivity to anisotropies in the gravitational wave background

Paul Frederik Depta, Valerie Domcke, Gabriele Franciolini +1

Pulsar Timing Array (PTA) observations have recently gathered substantial evidence for the existence of a gravitational wave background in the nHz frequency band. Searching for ani…

Primordial Black Holes: from Theory to Gravitational Wave Observations

G. Franciolini

Primordial Black Holes (PBH) can form in the early universe and might comprise a significant fraction of the dark matter. Interestingly, they are accompanied by the generation of G…

The Formation Probability of Primordial Black Holes

Matteo Biagetti, Valerio De Luca, Gabriele Franciolini +2

We calculate the exact formation probability of primordial black holes generated during the collapse at horizon re-entry of large fluctuations produced during inflation, such as th…

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…
