Revisiting the expected Micro-X signal from the 3.5 keV line
Denys Savchenko, Dmytro Iakubovskyi
One of the future instruments to resolve the origin of the unidentified 3.5 keV emission line is the Micro-X sounding rocket telescope. According to the estimate made in 2015, Micr…
21-cm observations and warm dark matter models
Alexey Boyarsky, Dmytro Iakubovskyi, Oleg Ruchayskiy +2
Observations of the redshifted 21-cm signal (in absorption or emission) allow us to peek into the epoch of "dark ages" and the onset of reionization. These data can provide a novel…
Simulating the dark matter decay signal from the Perseus galaxy cluster
Mark R. Lovell, Dmytro Iakubovskyi, David Barnes +4
The nearby Perseus galaxy cluster is a key target for indirect detection searches for decaying dark matter. We use the C-EAGLE simulations of galaxy clusters to predict the flux, w…
Surface brightness profile of the 3.5 keV line in the Milky Way halo
A. Boyarsky, D. Iakubovskyi, O. Ruchayskiy +1
We report a detection of 3.5 keV line in the Milky Way in 5 regions offset from the Galactic Center by distances from 10' to 35 degrees. We build an angular profile of this line an…
Dark matter model favoured by reionization data: 7 keV sterile neutrino vs cold dark matter
Anton Rudakovskyi, Dmytro Iakubovskyi
One of possible explanations of a faint narrow emission line at 3.5 keV reported in our Galaxy, Andromeda galaxy and a number of galaxy clusters is the dark matter made of 7 keV st…
Radial Profile of the 3.55 keV line out to in the Perseus Cluster
Jeroen Franse, Esra Bulbul, Adam Foster +10
The recent discovery of the unidentified emission line at 3.55 keV in galaxies and clusters has attracted great interest from the community. As the origin of the line remains uncer…
