Sterile neutrinos with pseudoscalar self-interactions and cosmology [PDF]
, 2015 Sterile neutrinos in the electronvolt mass range are hinted at by a number of terrestrial neutrino experiments. However, such neutrinos are highly incompatible with data from the Cosmic Microwave Background and large scale structure. This paper discusses

Sterile neutrino dark matter from right-handed neutrino oscillations [PDF]
, 2018 We study a scenario where sterile neutrino (either warm or cold) dark matter (DM) is produced through (nonresonant) oscillations among right-handed neutrinos (RHNs) and can constitute the whole DM in the Universe, in contrast to the conventional sterile ...

Reconciling present neutrino puzzles: Sterile neutrinos as mirror neutrinos [PDF]
Physical Review D, 1995 We suggest that recent neutrino puzzles that are the solar and atmospheric neutrino deficits as well as the possible neutrino oscillations reported by the LSND experiment and the possibility of massive neutrinos providing the hot component of the cosmological dark matter, can all be naturally explained by assuming existence of a mirror world described ...

Reionization in sterile neutrino cosmologies [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 We investigate the process of reionisation in a model in which the dark matter is a warm elementary particle such as a sterile neutrino. We focus on models that are consistent with the dark matter decay interpretation of the recently detected line at 3.5 keV in the X-ray spectra of galaxies and clusters.

New Journal of Physics, 2007 Neutrino masses are usually described by adding to the Standard Model some SU(2)-singlet fermions that have the Yukawa couplings, as well as some Majorana mass terms. The number of such fields and the scales of their Majorana masses are not known. Several independent observations point to the possibility that some of these singlets may have masses well

Constraining sterile neutrinos using reactor neutrino experiments [PDF]
Journal of High Energy Physics, 2014 Models of neutrino mixing involving one or more sterile neutrinos have resurrected their importance in the light of recent cosmological data. In this case, reactor antineutrino experiments offer an ideal place to look for signatures of sterile neutrinos due to their impact on neutrino flavor transitions.

Light Sterile Neutrinos in Cosmology and Short-Baseline Oscillation Experiments [PDF]
, 2013 We analyze the most recent cosmological data, including Planck, taking into account the possible existence of a sterile neutrino with a mass at the eV scale indicated by short-baseline neutrino oscillations data in the 3+1 framework.

Sterile neutrinos and future solar neutrino experiments [PDF]
Physics Letters B, 1994 It is shown that future solar neutrino experiments (SNO, Super-Kamiokande and others), in which high energy neutrinos will be detected (mostly from 8B decay), may allow to answer in a model independent way the question whether there are transitions of solar $ _e$'s into sterile states.
