The hot and dense early Universe combined with the promise of high-precision cosmological observations provide an intriguing laboratory for Beyond Standard Model (BSM) physics. We simulate the early Universe to examine the effects of the decay of thermally populated sterile neutrino states into Standard Model products around the time of weak decoupling. These decays deposit a significant amount of entropy into the plasma as well as produce a population of high-energy outof-equilibrium active… Expand


Possible hints of sterile neutrinos in recent measurements of the Hubble parameter
Local Universe observations find a value of the Hubble constant H 0 that is larger than the value inferred from the Cosmic Microwave Background and other early Universe measurements, assuming knownExpand
Heavy sterile neutrinos, entropy and relativistic energy production, and the relic neutrino background
We explore the implications of the existence of heavy neutral fermions (e.g., sterile neutrinos) for the thermal history of the early universe. In particular, we consider sterile neutrinos with restExpand
Production and evolution of perturbations of sterile neutrino dark matter
Sterile neutrinos, fermions with no standard model couplings [SU(2) singlets], are predicted by most extensions of the standard model, and may be the dark matter. I describe the nonthermal productionExpand
Lepton-number-driven sterile neutrino production in the early universe
We examine medium-enhanced, neutrino scattering-induced decoherent production of dark matter candidate sterile neutrinos in the early universe. In cases with a significant net lepton number we findExpand
Tau lepton asymmetry by sterile neutrino emission—moving beyond one-zone supernova models
The mixing of active neutrinos with their sterile counterparts with keV mass is known to have a potentially major impact on the energy loss from the supernova core. By relying on a set of threeExpand
Dark-matter sterile neutrinos in models with a gauge singlet in the Higgs sector
Sterile neutrino with mass of several keV can be the cosmological dark matter, can explain the observed velocities of pulsars, and can play an important role in the formation of the first stars. WeExpand
How to find neutral leptons of the νMSM
An extension of the Standard Model by three singlet fermions with masses smaller than the electroweak scale allows to explain simultaneously neutrino oscillations, dark matter and baryon asymmetry ofExpand
Pulsar kicks from a dark-matter sterile neutrino
We show that a sterile neutrino with mass in the 1-20 keV range and a small mixing with the electron neutrino can simultaneously explain the origin of the pulsar motions and the dark matter in theExpand
Bulk QCD thermodynamics and sterile neutrino dark matter
Author(s): Abazajian, KN; Fuller, GM | Abstract: We point out that the relic densities of singlet (sterile) neutrinos of interest in viable warm and cold dark matter scenarios depend on theExpand
We analyze the processes relevant for star formation in a model with dark matter in the form of sterile neutrinos. Sterile neutrino decays produce an X-ray background radiation that has a twofoldExpand
