From Evidence to Evident: Decisive Cosmological Evidence for the Normal Neutrino Mass Hierarchy
Raul Jimenez, Carlos Peña Garay, Fergus Simpson +1
Cosmological data have reached the precision needed to turn the neutrino mass ordering from a weak Bayesian preference into a decisive model-selection test. We compute the evidence…
The Coherence Principle: A Falsifiable Prior for Model Selection from the Grammar of Theories
Raul Jimenez, Carlos Peña Garay, Fergus Simpson +1
Bayesian model selection in cosmology and particle physics is often performed where posterior odds inherit a strong, often unacknowledged dependence on the prior assigned to compet…
Cross-correlations of the Cosmic Neutrino Background: HR-DEMNUni simulation analysis
Beatriz Hernández-Molinero, Matteo Calabrese, Carmelita Carbone +3
We use the high-resolution HR-DEMNUni simulations to compute cross-correlations of the Cosmic Neutrino Background quantities, like neutrino density, deflection angle, and velocity,…
Effects of the Cosmic Neutrino Background Capture on Astrophysical Objects
Beatriz Hernandez-Molinero, Raul Jimenez, Carlos Peña Garay
Low-energy neutrinos from the cosmic background are captured by objects in the sky that contain material susceptible of single beta decay. Neutrons, which compose most of a neutron…
