Bounds on Light Dark Matter
Alexey Boyarsky, Oleg Ruchayskiy
In this talk we review existing cosmological and astrophysical bounds on light (with the mass in keV - MeV range) and super-weakly interacting dark matter candidates. A particular…
Constraints on decaying Dark Matter from XMM-Newton observations of M31
Alexey Boyarsky, Dmytro Iakubovskyi, Oleg Ruchayskiy +1
We derive constraints on parameters of the radiatively decaying Dark Matter (DM) particles, using XMM-Newton EPIC spectra of the Andromeda galaxy (M31). Using the observations of t…
Anomaly induced effects in a magnetic field
Ignatios Antoniadis, Alexey Boyarsky, Oleg Ruchayskiy
We consider a modification of electrodynamics by an additional light massive vector field, interacting with the photon via Chern-Simons-like coupling. This theory predicts observab…
Search for the light dark matter with an X-ray spectrometer
Alexey Boyarsky, Jan Willem den Herder, Andrey Neronov +1
Sterile neutrinos with the mass in the keV range are interesting warm dark matter (WDM) candidates. The restrictions on their parameters (mass and mixing angle) obtained by current…
On the spectrum of relativistic Schroedinger equation in finite differences
V. A. Berezin, A. M. Boyarsky, A. Yu. Neronov
We develop a method for constructing asymptotic solutions of finite-difference equations and implement it to a relativistic Schroedinger equation which describes motion of a selfgr…
