Chandra observations of the hybrid morphology radio sources 3C 433 and 4C 65.15: FR IIs with asymmetric environments

Understand

We present Chandra observations of the hybrid morphology radio sources 3C 433 and 4C 65.15, two members of the rare class of objects possessing an FR I jet on one side of the core and an FR II lobe on the other.

• The X-ray spectrum of 3C 433 shows intrinsic absorption (with a column density of N_H=8e22 cm-2), such as is typical of FR II narrow-line radio galaxies.
• There is excess X-ray emission below 2 keV containing contributions from diffuse soft X-ray emission (likely hot gas with kT~1.2 keV) as well as from the nucleus.
• The core of 3C 433 is extended in hard X-rays, presumably due to X-ray emission from the inner-jet knot on the FR I side that is apparent in the radio map.
