Spectra of X-ray galaxies in filaments

Tugay A.V

Kyiv Shevchenko National University, Ukraine

Abstract

Large-scale structure of Universe consists of galaxy clusters connected by filaments. Single filaments can be detected at redshifts up to 0.15. The general characteriscis of X-ray spectra of Sloan Digital Sky Survey galaxies, that lies outside clusters, are considered in this work. Seyfert 1 AGN's are the main type of X-ray sources in the selected volume. X-ray spectra for 7 new bright galaxies were obtained from XMM-Neton archive.

Keywords: X-rays; galaxies; large-scale structure of Universe
