Cosmic ray astrophysics
Research Fields:
Astronomy
Previous and Current Research
In field of cosmic plasma physics we worked out approximate analytical methods for describing the motion of strong shocks in arbitrary non-uniform media and applied them to the investigation of Supernova remnants’ evolution in a nonuniform interstellar medium.
In field of cosmic ray astrophysics we investigated the sources, acceleration mechanisms and energy spectra of ultra high energy cosmic rays.
In field of cosmic topological defects’ physics we investigated the astrophysical signatures of cosmic strings.
Future Projects and Goals
We are the participants of the International Cherenkov Telescope Array (CTA) project. CTA is next generation ground-based observatory for gamma-ray astronomy at very high energies (https://www.cta-observatory.org/)
Methodological and Technical Expertise
Cosmic rays, shock waves in cosmic plasmas, Supernova remnants, cosmic strings.
