A deep look at the inner regions of the mini-BAL QSO PG 1126-041 with XMM-Newton

TL;DR

This paper reports on XMM-Newton observations of the mini-BAL QSO PG 1126-041, revealing a highly ionized X-ray absorbing gas outflow at high velocity, providing insights into quasar outflows.

Contribution

It presents the detection and analysis of a highly ionized, fast outflow in a mini-BAL quasar using X-ray observations, which is a novel insight into quasar winds.

Findings

Detection of highly ionized X-ray absorbing gas

Outflow velocity of approximately 15000 km/s

Implications for quasar wind models

Abstract

A long XMM-Newton observation of the mini-BAL QSO PG 1126-041 allowed us to detect a highly ionized phase of X-ray absorbing gas outflowing at v~15000 km/s. Physical implications are briefly discussed.
