The sample of eight LLAGNs: X-ray properties

TL;DR

This study investigates the X-ray spectral properties of a sample of 12 low-luminosity active galactic nuclei (LLAGN), analyzing available XMM-Newton observations to better understand their characteristics.

Contribution

The paper presents a new sample of LLAGN and analyzes their X-ray spectral properties, providing preliminary results and a foundation for future expanded studies.

Findings

Spectral fitting with power law + neutral hydrogen absorption

Analysis of 8 LLAGN with available XMM data

Initial results support further investigation into LLAGN X-ray properties

Abstract

LLAGN are very important objects for studying as they are found in a large fraction of all massive galaxies. Nevertheless this topic needs more investigation as fraction of LLAGN in all AGN are much more higher than fraction of researches dedicated to LLAGN among all AGN studies. The goal of our work is checking out X-ray properties of LLAGN. For this purpose we created a sample of LLAGN by selecting most prominent LLAGN from literature and analyzed their X-ray spectral properties. As a result, we obtained 12 LLAGN and for 8 of them XMM X-ray observations are available. The spectra from one XMM camera, PN, were fitted with power law + absorption of neutral hydrogen. In the current report we present the previous results of this study. We plan to increase numbers of objects in our future studies.
