We present a comprehensive review of keV-scale sterile neutrino Dark Matter, collecting
views and insights from all disciplines involved—cosmology, astrophysics, nuclear, and …

The identity of dark matter is a question of central importance in both astrophysics and
particle physics. In the past, the leading particle candidates were cold and collisionless, and …

This paper describes the physics case for a new fixed target facility at CERN SPS. The SHiP
(search for hidden particles) experiment is intended to hunt for new physics in the largely …

We detect a weak unidentified emission line at E=(3.55–3.57)±0.03 keV in a stacked XMM-
Newton spectrum of 73 galaxy clusters spanning a redshift range 0.01–0.35. When the full …

Neutrinos are the only particles in the Standard Model (SM) of particle physics that have only
been observed with left handed chirality to date. If right handed (RH) neutrinos exist, they …

We report a weak line at 3.52±0.02 keV in x-ray spectra of the Andromeda galaxy and the
Perseus galaxy cluster observed by the metal-oxide-silicon (MOS) and pn (PN) CCD …

We review sterile neutrinos as possible Dark Matter candidates. After a short summary on
the role of neutrinos in cosmology and particle physics, we give a comprehensive overview …

We detect a line at 3.539±0.011 keV in the deep exposure data set of the Galactic center
region, observed with the x-ray multi-mirror mission Newton. The dark matter interpretation …

Several recent works have reported the detection of an unidentified x-ray line at 3.55 keV,
which could possibly be attributed to the decay of dark matter (DM) particles in the halos of …

We have conducted N-body simulations of the growth of Milky Way-sized halos in cold and
warm dark matter cosmologies. The number of dark matter satellites in our simulated Milky …
