Abstract:
Surveying radio-loud active galaxies (AGNs) in the X-rays is a challenging task which difficulties are mainly driven by their low sky density (i.e. number of sources per square degree) in comparison with other AGN classes. On the other hand, discoveries achieved in the last two decades, based on Chandra observations, allowed us to study many aspects of their evolution. Given the observational evidence that radio-loud AGNs tend to live in galaxy-rich large-scale environments (i.e., galaxy groups or clusters), their X-ray observations are crucial to shed a light on the feedback mechanism. The main objective of this white paper is to highlight the importance of results achieved thanks to X-ray snapshot observations of radio-loud AGNs, in particular on the revised Third Cambridge catalog (3CR), to propose a selected sample of radio sources listed in the Bologna Sky Survey at 408 MHz (B2CAT), as cool-attitude targets for the Chandra mission. The 3CR Chandra snapshot survey represents a perfect example of how short-exposure X-ray observations can provide great discoveries.
