Constraining Extended Gamma-ray Emission from Galaxy Clusters
Jiaxin Han, Carlos S. Frenk, Vincent R. Eke +5
Cold dark matter models predict the existence of a large number of substructures within dark matter halos. If the cold dark matter consists of weakly interacting massive particles,…
Spectral and spatial variations of the diffuse gamma-ray background in the vicinity of the Galactic plane and possible nature of the feature at 130 GeV
Alexey Boyarsky, Denys Malyshev, Oleg Ruchayskiy
We study the properties of the diffuse gamma-ray background around the Galactic plane at energies 20 -- 200 GeV. We find that the spectrum of this emission possesses significant sp…
Light Sterile Neutrinos: A White Paper
K. N. Abazajian, M. A. Acero, S. K. Agarwalla +184
This white paper addresses the hypothesis of light sterile neutrinos based on recent anomalies observed in neutrino experiments and the latest astrophysical data.
Long-range magnetic fields in the ground state of the Standard Model plasma
Alexey Boyarsky, Oleg Ruchayskiy, Mikhail Shaposhnikov
In thermal equilibrium the ground state of the plasma of Standard Model particles is determined by temperature and exactly conserved combinations of baryon and lepton numbers. We s…
The inner structure of haloes in Cold+Warm dark matter models
Andrea V. Maccio', Oleg Ruchayskiy, Alexey Boyarsky +1
We analyze the properties of dark matter halos in the cold-plus-warm dark matter cosmologies (CWDM). We study their dependence on the fraction and velocity dispersion of the warm p…
Restrictions on the lifetime of sterile neutrinos from primordial nucleosynthesis
Oleg Ruchayskiy, Artem Ivashko
We analyze the influence of decaying sterile neutrinos with the masses in the range 1-140 MeV on the primordial Helium-4 abundance, explicitly solving the Boltzmann equations for a…
