Dark energy and neutrinos along the cosmic expansion history
Pietro Ghedini, Rasmi Hajjar, Olga Mena
Recent cosmological measurements are hinting that dark energy may evolve, with its equation of state, , even showing oscillatory patterns. In this work, we employ a…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Origin of cosmological neutrino mass bounds: background perturbations
Toni Bertólez-Martínez, Ivan Esteban, Rasmi Hajjar +2
The cosmological upper bound on the total neutrino mass is the dominant limit on this fundamental parameter. Recent observations-soon to be improved-have strongly tightened it, app…
Redshift Space Distortions corner interacting Dark Energy
Pietro Ghedini, Rasmi Hajjar, Olga Mena
Despite the fact that the CDM model has been highly successful over the last few decades in providing an accurate fit to a broad range of cosmological and astrophysical observat…
