X-ray spectroscopy of polar-scattered Seyfert 1 galaxies
Abstract
We present a spectral re-analysis of Fairall 51, optically a Seyfert 1 galaxy, which, however, shows a very strong polarization. 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 present results from a study of 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 estimated the location of the variable absorber to be 3 to 60 light days from the central engine, which indicates its origin in the Broad Line Region.
