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…
Extragalactic filament detection with a layer smoothing method
Anatoliy V. Tugay
Filaments are clearly visible in galaxy distributions, but they are hardly detected by computer algorithms. Most methods of filament detection can be used only with numerical simul…
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…
Determination of dark matter type by X-ray sources statistics
Anatoliy V. Tugay
The current cosmological model includes cold dark matter, which consists of massive nonrelativistic particles. There are also some observational and theoretical evidences for warm…
