Impact of Supercooling on Direct Searches for Dark Matter and Gravitational Wave Backgrounds
Davide Racco, Alfredo Stanzione
An interesting feature of a cosmological phase transition can be a stage of exponential expansion (supercooling). The modified expansion history and the entropy injection at reheat…
Understanding the Nature of Scalar-Induced Gravitational Waves
A. J. Iovino, G. Perna, D. Perrone +2
We offer a physical interpretation of the origin of the scalar-induced gravitational wave background, showing that it is mainly produced around the peaks of the scalar perturbation…
Probing Flavour Deconstruction via Primordial Gravitational Waves
Noemi Fabri, Gino Isidori, Davide Racco
We study the production of primordial gravitational waves (GWs) from first-order phase transitions (FOPTs) in extensions of the Standard Model based on Flavour Deconstruction (FD).…
Revisiting Isocurvature Bounds on the Minimal QCD Axion
Peter W. Graham, Davide Racco
The QCD axion has important connections to early universe cosmology. For example, it is often said that isocurvature limits rule out a combination of high axion decay constant, $f_…
Neutrino masses from large-scale structures: future sensitivity and theory dependence
Davide Racco, Pierre Zhang, Henry Zheng
In the incoming years, cosmological surveys aim at measuring the sum of neutrino masses , complementing the determination of their mass ordering from laboratory experiments.…
