Footprints of the QCD Crossover on Cosmological Gravitational Waves at Pulsar Timing Arrays
Gabriele Franciolini, Davide Racco, Fabrizio Rompineve
Pulsar Timing Arrays (PTAs) have reported evidence for a stochastic gravitational wave (GW) background at nHz frequencies, possibly originating in the early Universe. We show that…
Dark Sectors with Mass Thresholds Face Cosmological Datasets
Itamar J. Allali, Fabrizio Rompineve, Mark P. Hertzberg
Interacting dark sectors may undergo changes in the number of their relativistic species during the early universe, due to a mass threshold (similar to changes in the Standard…
Search for scalar induced gravitational waves in the International Pulsar Timing Array Data Release 2 and NANOgrav 12.5 years datasets
Virgile Dandoy, Valerie Domcke, Fabrizio Rompineve
We perform a Bayesian search in the latest Pulsar Timing Array (PTA) datasets for a stochastic gravitational wave (GW) background sourced by curvature perturbations at scales $10^5…
