Abstract

We present results of our analysis of the XMM-Newton and Swift observations of the galaxy with Sy 1.9 active nucleus Mrk 1498. We analyze the spectra obtained from three EPIC cameras (PN and both MOS) within the 0.2–12 keV energy range and Swift/BAT instrument within the range of 14-195 keV. We demonstrate that for the X-ray spectrum of the AGN in this galaxy the standard models taking into account only the emission reflected by the accretion disk are adequate, but also the more complicate model including both the absorption and reflection of the primary AGN emission on a gas-dust ring shaped torus-like structure. Also, in the X-ray spectrum we detected the components corresponding to the emission of diffuse collizionally-ionized gas, and the power-law spectrum of the scattered radiation.

Keywords: active galactic nuclei; X-ray spectra
