Updated constraints on massive neutrino self-interactions from cosmology in light of the tension
Shouvik Roy Choudhury, Steen Hannestad, Thomas Tram
We have updated the constraints on flavour universal neutrino self-interactions mediated by a heavy scalar, in the effective 4-fermion interaction limit. We use the relaxation time…
Updated constraints on decaying cold dark matter
Andreas Nygaard, Thomas Tram, Steen Hannestad
In this paper we update the constraints on the simple decaying cold dark matter (DCDM) model with dark radiation (DR) as decay product. We consider two different regimes of the lif…
Invisible neutrino decay in precision cosmology
Gabriela Barenboim, Joe Zhiyu Chen, Steen Hannestad +3
We revisit the topic of invisible neutrino decay in the precision cosmological context, via a first-principles approach to understanding the cosmic microwave background and large-s…
Euclid preparation: IX. EuclidEmulator2 -- Power spectrum emulation with massive neutrinos and self-consistent dark energy perturbations
Euclid Collaboration, M. Knabenhans, J. Stadel +131
We present a new, updated version of the EuclidEmulator (called EuclidEmulator2), a fast and accurate predictor for the nonlinear correction of the matter power spectrum. Percent-l…
Sterile neutrino self-interactions: tension and short-baseline anomalies
Maria Archidiacono, Stefano Gariazzo, Carlo Giunti +2
Sterile neutrinos with a mass in the eV range have been invoked as a possible explanation of a variety of short baseline (SBL) neutrino oscillation anomalies. However, if one consi…
MeV-scale reheating temperature and cosmological production of light sterile neutrinos
Takuya Hasegawa, Nagisa Hiroshima, Kazunori Kohri +3
We investigate how sterile neutrinos with a range of masses influence cosmology in MeV-scale reheating temperature scenarios. By computing the production of sterile neutrinos throu…
