Jets and outflows in Radio Galaxies: implications for AGN feedback

TL;DR

This paper investigates the properties of warm absorbers in Broad Line Radio Galaxies and explores their implications for understanding AGN feedback mechanisms in galaxy evolution.

Contribution

It presents the first detection of warm absorbers in two Broad Line Radio Galaxies and compares radio-loud and radio-quiet outflows to shed light on AGN feedback.

Findings

Detection of warm absorbers in 3C 382 and 3C 390.3

Analysis of the physical and energetic properties of the absorbing gas

Comparison between radio-loud and radio-quiet outflows

Abstract

One of the main debated astrophysical problems is the role of the AGN feedback in galaxy formation. It is known that massive black holes have a profound effect on the formation and evolution of galaxies, but how black holes and galaxies communicate is still an unsolved problem. For Radio Galaxies, feedback studies have mainly focused on jet/cavity systems in the most massive and X-ray luminous galaxy clusters. The recent high-resolution detection of warm absorbers in some Broad Line Radio Galaxies allow us to investigate the interplay between the nuclear engine and the surrounding medium from a different perspective. We report on the detection of warm absorbers in two Broad Line Radio Galaxies, 3C 382 and 3C 390.3, and discuss the physical and energetic properties of the absorbing gas. Finally, we attempt a comparison between radio-loud and radio-quiet outflows.
