Description
We present the results of our analysis of the X-ray spectra of a large subsample of active galactic nuclei (AGN) from the catalog of sources detected by the Mikhail Pavlinsky ART-XC telescope aboard the SRG orbital observatory during its all-sky survey (ARTSS1-5). The analysis is based on archival observations with the Swift/XRT telescope in the 1–10 keV energy range. For all sources, we derive, for the first time, estimates of the power-law continuum photon index, intrinsic absorption column density, and absorption-corrected X-ray flux. In addition, we present preliminary results of our analysis of optical spectra of AGN from the ARTSS1-5 catalog, obtained from the SDSS archive. Specifically, we report measurements of key parameters of broad and narrow emission lines. The study was carried out as part of a broader effort aimed at constructing a statistically complete multi-wavelength database of AGN from the ARTSS1–5 catalog.
