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…
Neutrino cosmology after DESI: tightest mass upper limits, preference for the normal ordering, and tension with terrestrial observations
Jun-Qian Jiang, William Giarè, Stefano Gariazzo +6
The recent DESI Baryon Acoustic Oscillation measurements have led to tight upper limits on the neutrino mass sum, potentially in tension with oscillation constraints requiring $\su…
Updating neutrino mass constraints with Background measurements
Deng Wang, Olga Mena, Eleonora Di Valentino +1
Low-redshift probes, such as Baryon Acoustic Oscillations (BAO) and Supernovae Ia luminosity distances, have been shown to be crucial for improving the bounds on the total neutrino…
Neutrinos in Cosmology
Eleonora Di Valentino, Stefano Gariazzo, Olga Mena
Neutrinos are the least known particle in the Standard Model of elementary particle physics. They play a crucial role in cosmology, governing the universe's evolution and shaping t…
How robust are the parameter constraints extending the CDM model?
Stefano Gariazzo, William Giarè, Olga Mena +1
We present model-marginalized limits on the six standard CDM cosmological parameters (, , , , and ), as well a…
A Semiblind Reconstruction of the History of Effective Number of Neutrinos Using CMB Data
Sarah Safi, Marzieh Farhang, Olga Mena +1
We explore the possibility of redshift-dependent deviations in the contribution of relativistic degrees of freedom to the radiation budget of the cosmos, conventionally parameteriz…
Lighting Dark Ages with Tomographic ISW Effect
Deng Wang, Olga Mena
The integrated Sachs-Wolfe effect (ISW) describes how CMB photons pick up a net blue or redshift when traversing the time-varying gravitational potentials between the last scatteri…
