Separating the spectral counterparts in NGC 1275/Perseus cluster in X-rays

Autor: Fedorova, Elena, Zadorozhna, Lidiia, Tugay, Anatolii, Pulatova, Nadiia, Ganz, Alexander, Gugnin, Olexandr

We develop the recipe to separate the spectral counterparts of the AGN NGC 1275 from the emission of the Perseus cluster surrounding it in the spectra observed by Suzaku/XIS cameras with no usage of the spectral fitting models. The Perseus cluster em

Advanced morphology of VIPERS galaxies

Autor: Gugnin, Olexandr, Tugay, Anatolii, Pulatova, Nadiia, Zadorozhna, Lidiia

We calculated morphological parameters for 70821 galaxies from VIPERS (spectroscopic galaxy survey performed on VIMOS spectroscope at VLT). These parameters includes Gini, M20, Concentration, Asymmetry and Smoothness. Results correlate with the distr

X-ray spectral features and classification of selected QSOs

Autor: Zadorozhna, Lidiia, Tugay, Anatolii, Pulatova, Nadiia, Maluy, Oleh

We present the results of a systematic analysis of the XMM-Newton spectra of nearby optically bright QSOs. The objects have been selected from X-ray Galaxy Catalog Xgal20. It is a catalog of 1172 manually identified and classified galaxies, obtained

The sample of eight LLAGNs: X-ray properties

Autor: Pulatova, Nadiia G., Tugay, Anatoliy V., Zadorozhna, Lidiia V.

Publikováno v: IAU Symposium 367/VIRTUAL Education and Heritage in the Era of Big Data in Astronomy, December 8-12, 2020

LLAGN are very important objects for studying as they are found in a large fraction of all massive galaxies. Nevertheless this topic needs more investigation as fraction of LLAGN in all AGN are much more higher than fraction of researches dedicated t
