# Luminosity - Spectral Index Dependence of X-ray Bright Seyfert Galaxies

## TL;DR

This study analyzes X-ray luminosities and spectral indices of 97 Seyfert 1 galaxies, suggesting a complex emission model and proposing a relation between black hole mass, merging stage, and X-ray properties.

## Contribution

It introduces a two-parametric emission model and links black hole mass and merging stage to X-ray spectral features in Seyfert galaxies.

## Key findings

- Distribution of luminosities and spectral indices appears random.
- A two-parametric emission model is necessary.
- Proposed relation between black hole mass, merging stage, and X-ray parameters.

## Abstract

X-ray luminosities and spectral indices of 97 bright Seyfert 1 galaxies from XMM archive are analyzed in this article. Distribution of these values is random so we conclude that the model of emission should be at least two-parametric. Within the merging model of AGN the relation between black hole mass, stage of merging and observable X-ray parameters is proposed.
