Unidentified line in x-ray spectra of the Andromeda galaxy and Perseus galaxy cluster.
- A. Boyarsky, O. Ruchayskiy, D. Iakubovskyi, J. Franse
- Physics, Medicine
- Physical review letters
- 17 February 2014
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-Newton… Expand
A facility to search for hidden particles at the CERN SPS: the SHiP physics case.
- S. Alekhin, W. Altmannshofer, +82 authors K. Zurek
- Physics, Medicine
- Reports on progress in physics. Physical Society
- 19 April 2015
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 unexplored… Expand
A facility to Search for Hidden Particles (SHiP) at the CERN SPS
- SHiP Collaboration M. Anelli, S. Aoki, +232 authors A. Zoccoli
- Physics
- 20 April 2015
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. Hidden… Expand
Lyman-alpha constraints on warm and on warm-plus-cold dark matter models
- A. Boyarsky, J. Lesgourgues, O. Ruchayskiy, M. Viel
- Physics
- 1 December 2008
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 up… Expand
Checking the Dark Matter Origin of a 3.53 keV Line with the Milky Way Center.
- A. Boyarsky, J. Franse, D. Iakubovskyi, O. Ruchayskiy
- Physics, Medicine
- Physical review letters
- 11 August 2014
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 of the signal… Expand
Self-consistent evolution of magnetic fields and chiral asymmetry in the early universe.
- A. Boyarsky, J. Fröhlich, O. Ruchayskiy
- Physics, Medicine
- Physical review letters
- 15 September 2011
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 previously… Expand
The haloes of bright satellite galaxies in a warm dark matter universe
- M. Lovell, V. Eke, +7 authors O. Ruchayskiy
- Physics
- 14 April 2011
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 circular… Expand
The Role of Sterile Neutrinos in Cosmology and Astrophysics
- A. Boyarsky, O. Ruchayskiy, M. Shaposhnikov
- Physics
- 30 December 2008
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 Standard… Expand
Light Sterile Neutrinos: A White Paper
- K. Abazajian, M. A. Acero, +184 authors H. Zhang
- Physics
- 18 April 2012
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
- A. Boyarsky, O. Ruchayskiy, D. Iakubovskyi
- Physics
- 28 August 2008
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
