A novel model-marginalized cosmological bound on the QCD axion mass
Eleonora Di Valentino, Stefano Gariazzo, William Giarè +3
We present model-marginalized limits on mixed hot dark matter scenarios, which consider both thermal neutrinos and thermal QCD axions. A novel aspect of our analyses is the inclusi…
Towards a reliable calculation of relic radiation from primordial gravitational waves
William Giarè, Matteo Forconi, Eleonora Di Valentino +1
Inflationary gravitational waves, behaving as additional radiation in the Early Universe, can increase the effective number of relativistic species () by a further cor…
Revealing the effects of curvature on the cosmological models
Weiqiang Yang, William Giarè, Supriya Pan +3
In this paper we consider the effects of adding curvature in extended cosmologies involving a free-to-vary neutrino sector and different parametrizations of Dark Energy (DE). We ma…
Is the Harrison-Zel'dovich spectrum coming back? ACT preference for and its discordance with Planck
William Giarè, Fabrizio Renzi, Olga Mena +2
The Data Release 4 of the Atacama Cosmology Telescope (ACT) shows an agreement with an Harrison-Zel'dovich primordial spectrum (), introducing a tension with a…
Quantifying the global "CMB tension" between the Atacama Cosmology Telescope and the Planck satellite in extended models of cosmology
Eleonora Di Valentino, William Giarè, Alessandro Melchiorri +1
We study the global agreement between the most recent observations of the Cosmic Microwave Background temperature and polarization anisotropies angular power spectra released by th…
Health checkup test of the standard cosmological model in view of recent Cosmic Microwave Background Anisotropies experiments
Eleonora Di Valentino, William Giarè, Alessandro Melchiorri +1
We present an updated data-analysis comparison of the most recent observations of the Cosmic Microwave Background temperature anisotropies and polarization angular power spectra re…
Cosmological Bound on the QCD Axion Mass, Redux
Francesco D'Eramo, Eleonora Di Valentino, William Giarè +5
We revisit the joint constraints in the mixed hot dark matter scenario in which both thermally produced QCD axions and relic neutrinos are present. Upon recomputing the cosmologica…
Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies
Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim +200
In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological…
