COSMOLOGY OF “VISIBLE ” STERILE NEUTRINOS ∗
, 2004
"... We point out that in scenarios with a low reheating temperature TR << 100 MeV at the end of (the last episode of) inflation or entropy production, the abundance of sterile neutrinos becomes largely independent of their coupling to active neutrinos. Thus, cosmological bounds become less stringe ..."

Sterile Neutrinos and Supernova Nucleosynthesis
, 1995
"... The role of the sterile neutrinos to the r-process nucleosynthesis in supernova explosions is studied. Previously it has been argued that a large part of neutrino mixing can be excluded if the supernovae are the origin of the heavy elements. It is shown that a conversion to sterile neutrinos ma ..."

AXINO AS A STERILE NEUTRINO
"... We present a supersymmetric axion model in which the fermionic superpartner of axion, i.e. the axino, corresponds to a sterile neutrino which would accommodate the LSND data with atmospheric and solar neutrino oscillations. ..."

LOCAL DEMANDS ON STERILE NEUTRINOS
, 2005
"... In a model independent manner, we explore the local implications of a single neutrino oscillation measurement which cannot be reconciled within a three-neutrino theory. We examine this inconsistency for a single region of baseline to neutrino energy L/E. Assuming that sterile neutrinos account for t ..."

Sterile neutrino states
, 2006
"... Neutrino masses are likely to be a manifestation of the right-handed, or sterile neutrinos. The number of sterile neutrinos and the scales of their Majorana masses are unknown. We explore theoretical arguments in favor of the high and low scale seesaw mechanisms, review the existing experimental res ..."

STERILE NEUTRINOS IN PARTICLE PHYSICS
, 2007
"... Abstract. 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 t ..."

to the possibility that some of these singlets may have masses well below the electroweak scale. A sterile neutrino with mass of a few keV can account for cosmological dark matter. The same particle would be emitted anisotropically from a cooling neutron star born in a supernova explosion. This anisotropy can
Searching for sterile neutrinos in ice
"... Oscillation interpretation of the results from the LSND, MiniBooNE and some other experiments requires existence of sterile neutrino with mass ∼ 1 eV and mixing with the active neutrinos |Uµ0|2 ∼ (0.02 − 0.04). It has been realized some time ago that existence of such a neutrino affects significantl ..."
