TL;DR
This study uses Chandra X-ray observations to analyze the environment of powerful radio sources from the Second Bologna Catalog, revealing nuclear activity, hot gas, and extended emission linked to galaxy clusters and groups.
Contribution
First X-ray survey of B2CAT radio sources combining imaging and spectral analysis, identifying extended emission and hot gas properties with implications for galaxy cluster environments.
Findings
Detected X-ray nuclei in 28 sources
Identified extended X-ray emission in five sources
Hot gas temperatures around 2 keV, linked to galaxy clusters and groups
Abstract
We present the first results of the Chandra Cool Targets (CCT) survey of the Second Bologna Catalog (B2CAT) of powerful radio sources, aimed at investigating the extended X-ray emission surrounding these sources. For the first 33 sources observed in the B2CAT CCT survey, we performed both imaging and spectral X-ray analysis, producing multi-band Chandra images, and compared them with radio observations. To evaluate the presence of extended emission in the X-rays, we extracted surface flux profiles comparing them with simulated ACIS Point Spread Functions. We detected X-ray nuclear emission for 28 sources. In addition, we detected 8 regions of increased X-ray flux originating from radio hot-spots or jet knots, and a region of decreased flux, possibly associated with an X-ray cavity. We performed X-ray spectral analysis for 15 nuclei and found intrinsic absorption significantly larger…
