X-ray Bright Sources in the Field of Active Galactic Nuclei MKN 205

TL;DR

This study detects and analyzes three bright X-ray sources near MKN 205, classifying them and examining their spectra to understand their nature and the presence of soft excess emissions.

Contribution

First detailed spectral analysis of three non-target X-ray sources in the field of MKN 205, including classification and absorption effects.

Findings

Detection of three bright X-ray sources in the field of MKN 205.

Spectral analysis reveals thermal and non-thermal components, with some sources showing intrinsic absorption.

Evidence of soft excess emission possibly from accretion disc or reprocessing layers.

Abstract

A three bright X-ray non-target sources are detected in the field of the seyfert 1 galaxy MKN 205. These sources are classified as optically Early-type galaxy, BLAGN, and NELG (NED, SIMBAD, and AXIS). The spectrum analysis is made for these objects using thermal models and non-thermal models, modified by interstellar absorption. In some objects we can not distinguish between the thermal and non-thermal models of the hard components from the spectrum alone. The presence of intrinsic absorption is tested by photoelectric absorption at the redshift of the sources, and we assumed the flux distribution is affected by the intrinsic absorption in some sources. A black body component used to test the presence of soft excess in some spectra, which has been interpreted as primary emission from the accretion disc or as secondary radiation form the reprocessing of the hard X-ray in the surface layers of the disc.
