The matter power spectrum at comoving scales of $(1\ensuremath{-}40){h}^{\ensuremath{-}1}\text{ }\text{ }\mathrm{Mpc}$ is very sensitive to the presence of Warm Dark Matter (WDM) particles with large free-streaming lengths. We present constraints on the mass of WDM particles from a combined analysis of the matter power spectrum inferred from the large samples of high-resolution high signal-to-noise Lyman-$\ensuremath{\alpha}$ forest data of Kim et al. (2004) and Croft et al. (2002) and the… 
Dark matter sterile neutrinos in stellar collapse: Alteration of energy/lepton number transport and a mechanism for supernova explosion enhancement
We investigate matter-enhanced Mikheyev-Smirnov-Wolfenstein (MSW) active-sterile neutrino conversion in the ${\ensuremath{\nu}}_{e}\ensuremath{\rightleftharpoons}{\ensuremath{\nu}}_{s}$ channel in
Neutrino minimal standard model predictions for neutrinoless double beta decay
Prediction of the effective Majorana mass for neutrinoless double $\ensuremath{\beta}$ decay in a simple extension of the standard model ($\ensuremath{\nu}\mathrm{MSM}$) is given. The model adds
Probing the nature of dark matter with cosmic x rays : Constraints from dark blobs and grating spectra of galaxy clusters
Gravitational lensing observations of galaxy clusters have identified dark matter blobs with remarkably low baryonic content. We use such a blob to probe the particle nature of dark matter with x-ray
Constraining the non-gravitational scattering of baryons and dark matter with early cosmic structure formation
We derive new constraints on the non-gravitational baryon-dark matter scattering (BDMS) by evaluating the mass thresholds of dark matter (DM) haloes in which primordial gas can cool efficiently to
Toward a General Parameterization of the Warm Dark Matter Halo Mass Function
Studies of flux anomalies statistics and perturbations in stellar streams have the potential to constrain models of warm dark matter (WDM), including sterile neutrinos. Producing these constraints
Lepton-number violation and right-handed neutrinos in Higgsless effective theories
Following previous work, we identify a symmetry ${S}_{\mathrm{nat}}$ that generalizes the concept of custodial symmetry, keeping under control deviations from the standard model (SM). To realize
Constraining warm dark matter power spectrum using the cross-correlation of HI 21 cm signal and the Lyman-α forest
We have considered the prospects for measuring the cross Warm Dark Matter (WDM) power spectrum of the redshifted HI 21-cm signal and the Lyman-$\alpha$ forest and thereby constraining WDM mass using
Implications of Milky Way substructures for the nature of dark matter
We study how the indirect observation of dark matter substructures in the Milky Way, using recent stellar stream studies, translates into constraints for different dark matter models. Particularly,
What if ALP dark matter for the XENON1T excess is the inflaton
The recent XENON1T excess in the electron recoil data can be explained by anomaly-free axion-like particle (ALP) dark matter with mass $m_\phi = 2.3 \pm 0.2\,$keV and the decay constant $f_\phi/q_e
Squeezing the window on isocurvature modes with the Lyman-{alpha} forest
Various recent studies proved that cosmological models with a significant contribution from cold dark matter isocurvature perturbations are still compatible with most recent data on cosmic microwave

Sterile neutrinos as dark matter.
TLDR
This model is reexamine and it is found that hot, warm, and cold dark matter are all possibilities and the number density of sterile neutrinos is proportional to [mu][sup 2]/M so that the energy density today is independent of M, which is crucial in determining the large scale structure of the Universe.
