Infrared counterparts of X-ray galaxies
A. Tugay, S. Shevchenko
Population studies of the extragalactic objects are a major part of the universe large-scale structure study. Apart from radio, infrared, and visible wavelength bands, observations…
Luminosity - Spectral Index Dependence of X-ray Bright Seyfert Galaxies
V. A. Sadova, A. V. Tugay
X-ray luminosities and spectral indices of 97 bright Seyfert 1 galaxies from XMM archive are analyzed in this article. Distribution of these values is random so we conclude that th…
Surface Brightness Profiles of Seyfert Galaxies
A. V. Tugay, S. L. Shihov
We built r-band surface brightness profiles by SDSS data for 16 Seyfert galaxies observed in Crimean Astrophysical Observatory. Obtained profiles can be used for finding more accur…
X-ray galaxies in nearby filaments
Anatoliy V. Tugay
New sample of X-ray galaxies selected from 2XMMi catalogue in SDSS region is analysed in this work. Spatial distribution and X-ray AGN spectral properties are discussed. A new meth…
Bright X-ray galaxies in SDSS filaments
A. V. Tugay
Eighteen bright X-ray emitting galaxies were found in nearby filaments within SDSS region. Basic X-ray spectral parameters were estimated for these galaxies using power law model w…
