Unidentified line in x-ray spectra of the Andromeda galaxy and Perseus galaxy cluster.
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 p-n (PN) CCD cameras of the XMM-NewtonExpand

A facility to search for hidden particles at the CERN SPS: the SHiP physics case.
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 unexploredExpand

A facility to Search for Hidden Particles (SHiP) at the CERN SPS
A new general purpose fixed target facility is proposed at the CERN SPS accelerator which is aimed at exploring the domain of hidden particles and make measurements with tau neutrinos. HiddenExpand

Lyman-alpha constraints on warm and on warm-plus-cold dark matter models
We revisit Lyman-alpha bounds on the dark matter mass in Lambda Warm Dark Matter (Lambda-WDM) models, and derive new bounds in the case of mixed Cold plus Warm models (Lambda-CWDM), using a set upExpand

Self-consistent evolution of magnetic fields and chiral asymmetry in the early universe.
We show that the evolution of magnetic fields in a primordial plasma, filled with standard model particles at temperatures T≳10 MeV, is strongly affected by the chiral anomaly-an effect previouslyExpand

The haloes of bright satellite galaxies in a warm dark matter universe
High-resolution N-body simulations of galactic cold dark matter haloes indicate that we should expect to find a few satellite galaxies around the Milky Way whose haloes have a maximum circularExpand

The Role of Sterile Neutrinos in Cosmology and Astrophysics
We present a comprehensive overview of an extension of the Standard Model that contains three right-handed (sterile) neutrinos with masses below the electroweak scale [the Neutrino Minimal StandardExpand

Light Sterile Neutrinos: A White Paper
This white paper addresses the hypothesis of light sterile neutrinos based on recent anomalies observed in neutrino experiments and the latest astrophysical data.

A lower bound on the mass of dark matter particles
We discuss the bounds on the mass of Dark Matter (DM) particles, coming from the analysis of DM phase-space distribution in dwarf spheroidal galaxies (dSphs). After reviewing the existing approaches,Expand
