Our research is related to theoretical astroparticle physics, cosmology, studies of interstellar medium and magnetic fields, and astrophysical variable objects. This research is tightly connected to the following international projects: LOFAR (The Low Frequency Array), SKA (Square Kilometer Array), MAGIC (Major Atmospheric Gamma Imaging Cherenkov Telescopes), satellite Gaia, and LSST (Legacy Survey of Space and Time).
