X-rays from a radio-loud compact BAL Quasar 1045+352 and the nature of outflows in radio-loud BAL Quasars

TL;DR

This study investigates the X-ray properties of a radio-loud BAL quasar 1045+352, analyzing its spectral energy distribution and exploring the origins of its X-ray emission, with implications for understanding outflows and jet interactions in such quasars.

Contribution

The paper presents new X-ray observations of a complex radio-loud BAL quasar and models its spectral energy distribution, highlighting the role of inverse-Compton jet emission in X-ray production.

Findings

X-ray emission can be explained by inverse-Compton processes in the jet.

No correlation found between X-ray and radio luminosities in the sample.

X-ray luminosities and absorption vary widely among radio-loud BAL quasars.

Abstract

We present new results on X-ray properties of radio loud broad absorption line (BAL) quasars and focus on broad-band spectral properties of a high ionization BAL (HiBAL) compact steep spectrum (CSS) radio-loud quasar 1045+352. This HiBAL quasar has a very complex radio morphology indicating either strong interactions between a radio jet and the surrounding interstellar medium or a possible re-start of the jet activity. We detected 1045+352 quasar in a short 5 ksec Chandra ACIS-S observation. We applied theoretical models to explain spectral energy distribution (SED) of 1045+352 and argue that non-thermal, inverse-Compton emission from the innermost parts of the radio jet can account for a large fraction of the observed X-ray emission. In our analysis we also consider a scenario in which the observed X-ray emission from radio-loud BAL quasars can be a sum of inverse-Compton jet X-ray emission and optically thin corona X-ray emission. We compiled a sample of radio-loud BAL quasars that were observed in X-rays to date and report no correlation between their X-ray and radio luminosity. However, the radio-loud BAL quasars show a large range of X-ray luminosities and absorption columns. This is consistent with the results obtained earlier for radio-quiet BAL quasars and may indicate an orientation effect in BAL quasars or more complex dependence between X-ray emission, radio emission and an orientation based on the radio morphology.
