Scientific paper

We present our understanding from a deep Chandra observations of 3C449 complemented with the archival Very Large Array radio observations, a canonical FR I radio galaxy, to study a large scale gas emission in a nearby (z = 0.017) 1.5 keV group. We find multiple surface brightness discontinuities in the gas, probably shocks, which are indicative of the supersonic inflation of the radio lobes. We also find X-ray cavities in the group gas coincident with the radio lobes. Surprisingly, there is no X-ray synchrotron emission associated with the inner jet at flux levels well below that observed in other nearby Fanaroff-Riley Class I sources.
