  • Bright X-ray galaxies in SDSS filaments 
    Tugay, A.V. (Advances in Astronomy and Space Physics, 2013)
    Eighteen bright X-ray emitting galaxies were found in nearby filaments within the SDSS region. Basic X-ray spectral parameters were estimated for these galaxies using a power law model with photoelectric absorption. A close ...
  • Extragalactic filament detection with a layer smoothing method 
    Tugay, A.V. (Advances in Astronomy and Space Physics, 2014)
    Filaments are clearly visible in galaxy distributions, but they are dificult to detect by computer algorithms. Most methods of filament detection can be used only with numerical simulations of a large-scale structure. New ...
  • The luminosity - spectral index dependence of the X-ray bright Seyfert galaxies 
    Sadova, V.A.; Tugay, A.V. (Advances in Astronomy and Space Physics, 2015)
    X-ray luminosities and spectral indices of 97 bright Seyfert 1 (Sy1) galaxies from the XMM-Newton archive are analysed in this article. Distribution of these values is random, so we conclude that the model of emission ...
