Constraints on warm dark matter from UV luminosity functions of high-z galaxies with Bayesian model comparison

Anton Rudakovskyi, Andrei Mesinger, Denys Savchenko +1

The number density of small dark matter (DM) halos hosting faint high-redshift galaxies is sensitive to the DM free-streaming properties. However, constraining these DM properties…

Can EDGES observation favour any dark matter model?

Anton Rudakovskyi, Denys Savchenko, Maksym Tsizh

The recent detection of the 21-cm absorption signal by the EDGES collaboration has been widely used to constrain the basic properties of dark matter particles. However, extracting…

New model of density distribution for fermionic dark matter halos

A. Rudakovskyi, D. Savchenko

In this paper, we formulate a new model of density distribution for halos made of warm dark matter (WDM) particles. The model is described by a single microphysics parameter - the…

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…

New mass bound on fermionic dark matter from a combined analysis of classical dSphs

Denys Savchenko, Anton Rudakovskyi

Dwarf spheroidal galaxies (dSphs) are the most compact dark matter-dominated objects observed so far. The Pauli exclusion principle limits the number of fermionic dark matter parti…

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…
