We present the first results of the Chandra Cool Targets (CCT) survey of theSecond Bologna Catalog (B2CAT) of powerful radio sources, aimed atinvestigating the extended X-ray emission surrounding these sources. For thefirst 33 sources observed in the B2CAT CCT survey, we performed both imagingand spectral X-ray analysis, producing multi-band Chandra images, and comparedthem with radio observations. To evaluate the presence of extended emission inthe X-rays, we extracted surface flux profiles comparing them with simulatedACIS Point Spread Functions. We detected X-ray nuclear emission for 28 sources.In addition, we detected 8 regions of increased X-ray flux originating fromradio hot-spots or jet knots, and a region of decreased flux, possiblyassociated with an X-ray cavity. We performed X-ray spectral analysis for 15nuclei and found intrinsic absorption significantly larger than the Galacticvalues in four of them. We detected significant extended X-ray emission in fivesources, and fitted their spectra with thermal models with gas temperatures$\sim 2 \text{ keV}$. In the case of B2.1 0742+31, the surrounding hot gas iscompatible with the ICM of low luminosity clusters of galaxies, while the X-raydiffuse emission surrounding the highly disturbed WAT B2.3 2254+35 features aluminosity similar to those of relatively bright galaxy groups, although itstemperature is similar to those of low luminosity galaxy clusters. Theseresults highlight the power of the low-frequency radio selection, combined withshort Chandra snapshot observations, to investigate the properties of the X-rayemission from radio sources.
