FERO (Finding Extreme Relativistic Objects): relativistic Iron K alpha lines in type 1 AGN

TL;DR

The FERO project systematically analyzes X-ray spectra of Type 1 AGN to detect relativistic Iron K alpha lines, providing insights into the relativistic effects near supermassive black holes.

Contribution

This study introduces a comprehensive analysis of relativistic Iron lines in a large sample of AGN using a full relativistic modeling approach.

Findings

Detection of relativistic Iron lines in a subset of AGN

Systematic fitting methodology established for X-ray spectra

Insights into the relativistic environment near black holes

Abstract

The observational evidence for AGN relativistic Iron lines is very much debated. To address this topic, the FERO project makes use of the largest sample of X-ray spectra of radio quiet Type 1 AGN available in the XMM-Newton archive. We perform a systematic fit of the individual sources using a full relativistic code. Results on the first part of the project are presented here.
