A novel approach to quantifying the sensitivity of current and future cosmological datasets to the neutrino mass ordering through Bayesian hierarchical modeling

Mena, Olga; Gerbino, Martina; Lattanzi, Massimiliano +1 more

We present a novel approach to derive constraints on neutrino masses, as well as on other cosmological parameters, from cosmological data, while taking into account our ignorance of the neutrino mass ordering. We derive constraints from a combination of current as well as future cosmological datasets on the total neutrino mass M_ν and on…

A combined view of sterile-neutrino constraints from CMB and neutrino oscillation measurements

Bridle, Sarah; Elvin-Poole, Jack; Evans, Justin +3 more

We perform a comparative analysis of constraints on sterile neutrinos from the Planck experiment and from current and future neutrino oscillation experiments (MINOS, IceCube, SBN). For the first time, we express joint constraints on N_eff and m_eff^sterile from the CMB in the Δm², sin² ⁡ 2 θ para…

Asymmetric Dark Matter in the shear-dominated universe

Iminniyaz, Hoernisa

We explore the relic abundance of asymmetric Dark Matter in shear-dominated universe in which it is assumed the universe is expanded anisotropically. The modified expansion rate leaves its imprint on the relic density of asymmetric Dark Matter particles if the asymmetric Dark Matter particles are decoupled in shear dominated era. We found the reli…
