Abstract:
We propose a deep Chandra observation of a powerful young radio source in an interesting phase of the feeding and feedback cycle. The compact radio source is embedded in the rich environment undisturbed by the past radio outbursts. We will study the X-ray properties of the hot gas using sub-arcsec capabilities of Chandra and investigate physical processes responsible for triggering powerful radio jets.
