Learning how to surf: Reconstructing the propagation and origin of gravitational waves with Gaussian Processes
Guadalupe Cañas-Herrera, Omar Contigiani, Valeri Vardanyan
Soon, the combination of electromagnetic and gravitational signals will open the door to a new era of gravitational-wave (GW) cosmology. It will allow us to test the propagation of…

Bayesian reconstruction of the inflaton's speed of sound using CMB data
Guadalupe Cañas-Herrera, Jesús Torrado, Ana Achúcarro
We update the search for features, due to transient reductions in inflaton's speed of sound, in the Cosmic Microwave Background (CMB) angular power spectrum using Planck 2018 tempe…

Cross-correlation of the astrophysical gravitational-wave background with galaxy clustering
Guadalupe Cañas-Herrera, Omar Contigiani, Valeri Vardanyan
We investigate the correlation between the distribution of galaxies and the predicted gravitational-wave background of astrophysical origin. We show that the large angular scale an…
