Primordial gravitational wave backgrounds from phase transitions with next generation ground based detectors
Chiara Caprini, Oriol Pujolàs, Hippolyte Quelquejay-Leclere +2
Third generation ground-based gravitational wave (GW) detectors, such as Einstein Telescope and Cosmic Explorer, will operate in the Hz frequency band, with a b…
Reduced Hubble Tension in Dark Radiation Models after DESI 2024
Itamar J. Allali, Alessio Notari, Fabrizio Rompineve
We investigate the presence of extra relativistic degrees of freedom in the early Universe, contributing to the effective number of neutrinos , as $ΔN_\text{eff}\equi…
Collapsing Domain Wall Networks: Impact on Pulsar Timing Arrays and Primordial Black Holes
Ricardo Z. Ferreira, Alessio Notari, Oriol Pujolàs +1
Unstable domain wall (DW) networks in the early universe are cosmologically viable and can emit a large amount of gravitational waves (GW) before annihilating. As such, they provid…
