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…
