The theory of gamma-rays generation by relativistic electrons and protons, accelerated in the shock fronts of supernovae remnants, has been developed, the influence of galaxy magnetic field on supernovae remnants evolution at the post-adiabatic expansion stage has been studied, the methods of analysis and numerical modeling of brightness surface maps of supernovae remnants in different wavelength ranges of electromagnetic radiation, from radio to gamma, have been created. Using the cluster analysis method it was found that about half of all open star clusters of the Galaxy form the non-random structures - cluster of clusters (taxon), or star complex. The semianalytic model of galaxy and galaxy clusters formation, allowing to calculate the redshift dependence of quasar number density, halo number density parameter for structures of different mass and halo mass functions from sub-galactic up to galaxy clusters scales, has been created. The telescope AZT-14 has been upgraded and the 250-mm telescope for CCD photometric observations of eclipsing stars has been improved.
