Pseudoscalar sterile neutrino self-interactions in light of Planck, SPT and ACT data
Mattia Atzori Corona, Riccardo Murgia, Matteo Cadeddu +4
We reassess the viability of a cosmological model including a fourth additional sterile neutrino species that self-interacts through a new pseudoscalar degree of freedom. We perfor…
Late time interacting cosmologies and the Hubble constant tension
Stefano Gariazzo, Eleonora Di Valentino, Olga Mena +1
In this manuscript we reassess the potential of interacting dark matter-dark energy models in solving the Hubble constant tension. These models have been proposed but also question…
Light Sterile Neutrinos
Stefano Gariazzo
We review the status of light sterile neutrino searches, motivated by the original Short BaseLine (SBL) anomalies. Here, we discuss how sterile neutrino properties can be constrain…
Cosmological radiation density with non-standard neutrino-electron interactions
Pablo Martínez-Miravé
Non-standard interactions (NSI) between neutrinos and electrons can significantly modify the decoupling of neutrinos from the plasma. These interactions have two effects on the ove…
Minimal dark energy: key to sterile neutrino and Hubble constant tensions?
Eleonora Di Valentino, Stefano Gariazzo, Carlo Giunti +3
Minimal dark energy models, described by the same number of free parameters of the standard cosmological model with cold dark matter plus a cosmological constant to parameterize th…
Implementation and Optimization of the PTOLEMY Transverse Drift Electromagnetic Filter
A. Apponi, M. G. Betti, M. Borghesi +53
The PTOLEMY transverse drift filter is a new concept to enable precision analysis of the energy spectrum of electrons near the tritium beta-decay endpoint. This paper details the i…
On the most constraining cosmological neutrino mass bounds
Eleonora Di Valentino, Stefano Gariazzo, Olga Mena
We present here up-to-date neutrino mass limits exploiting the most recent cosmological data sets. By making use of the Cosmic Microwave Background temperature fluctuation and pola…
Cosmological radiation density with non-standard neutrino-electron interactions
Pablo F. de Salas, Stefano Gariazzo, Pablo Martínez-Miravé +2
Neutrino non-standard interactions (NSI) with electrons are known to alter the picture of neutrino decoupling from the cosmic plasma. NSI modify both flavour oscillations through m…
PArthENoPE Revolutions
S. Gariazzo, P. F. de Salas, O. Pisanti +1
This paper presents the main features of a new and updated version of the program PArthENoPE, which the community has been using for many years for computing the abundances of ligh…
