Extra Radiation Cosmologies: Implications of the Hubble Tension for eV-scale Neutrinos
Helena García Escudero, Kevork N. Abazajian
We present a new analysis on sterile neutrino cosmologies using the Dark Energy Spectroscopic Instrument (DESI) second data release (DR2) baryon acoustic oscillation (BAO) measurem…
Cosmic Structure Strikes Back: The Elimination of Vector-Mediated Nonstandard Interaction Models as a Mechanism for Sterile Neutrino Dark Matter Production
Cannon M. Vogel, Helena García Escudero, Kevork N. Abazajian
We revisit sterile-neutrino production enabled by nonstandard interactions (NSI) among active neutrinos mediated by new bosons. We focus on vector mediators, including neutrinophil…
Return of the Lepton Number: Sterile Neutrino Dark Matter Production and the Revival of the Shi-Fuller Mechanism
Cannon M. Vogel, Helena García Escudero, Julien Froustey +1
We explore resonant production of sterile neutrino dark matter via the Shi-Fuller (SF) mechanism, revisiting its cosmological viability in light of recent results demonstrating tha…
