Hard X-ray surveys and the local AGN population
Sergey Sazonov
TL;DR
This paper reviews recent advances in understanding the local active galactic nucleus (AGN) population through large-area hard X-ray surveys, emphasizing the relationship between obscured AGN fraction and X-ray luminosity.
Contribution
It provides new insights into the obscured AGN fraction using data from IBIS/INTEGRAL surveys, highlighting luminosity dependence.
Findings
Obscured AGN fraction decreases with increasing X-ray luminosity
Large-area hard X-ray surveys effectively identify local AGN populations
IBIS/INTEGRAL data enhances understanding of AGN obscuration properties
Abstract
We discuss some recent achievements in our understanding of the local AGN population based on large-area hard X-ray surveys (in particular, by the IBIS instrument aboard INTEGRAL), focusing on the issue of the fraction of obscured AGN as a function of hard X-ray luminosity.
