X-ray spectroscopy of polar-scattered Seyfert 1 galaxies
 Mikušincová, Romana ; Svoboda, Jiří (advisor) ; Horák, Jiří (referee)
In this thesis we present a spectral re-analysis of the Fairall 51 galaxy. It is optically a Seyfert 1 galaxy. It does, however, show a very strong polarization in the optical spectrum and as this feature is not characteristic for Seyfert 1 objects, this galaxy may represent a borderline object between Seyfert 1 and Seyfert 2 galaxies and provide with valuable information about the structure of Active Galactic Nuclei. We studied two archival sets of observations performed in September 2005 and March 2006 by the European satellite XMM-Newton and four observations performed in September 2013 by the Japanese observatory Suzaku. It follows from the spectral analysis that there are at least two or three ionized absorbers in the studied AGN. Based on the spectral variability, we were also able to estimate the location of the variable absorber which appears to be 3 to 60 light days from the central engine, which indicates its origin in the Broad Line Region. 1
