ANALYTICAL-NUMERICAL METHODS OF INVESTIGATION OF PROCESSES IN THE SUPERNOVA REMNANTS
According to the scientific report at the meeting of the Presidium of NAS of Ukraine, March 11, 2020

Emission caused by particles accelerated on the shock wave in supernova remnants (SNRs) is a source of information about the kinetics of accelerated particles and morphology of objects. Analysis of spectral radiation is one of sources for investigation of particle acceleration. Development of observational astronomy allowed the production of surface brightness distribution maps of SNRs with good resolution in all electromagnetic domains from radio to gamma-rays. The availability of such data requires the construction of models for simulations of the surface brightness distribution maps of SNRs.
Keywords: shock wave, supernova remnants, acceleration of elementary particles, emission of acceleration particles, gamma-rays, maps of the surface brightness distribution.
