Scientific paper

We propose a 25-ks Chandra/ACIS-S observation of the extended narrow-line region (ENLR) in the radio galaxy Coma A - the first X-ray imaging observations of this powerful radio source. We will use Chandra's superb spatial resolution to examine the relationship between the X-ray-emitting shock-heated gas, radio jet, and optical line-emission. We will determine the role of shocks in imparting energy into the ambient IGM and assess the part that ionizing nuclear radiation plays in governing the ENLR. Coma A has key implications for AGN feedback: it is a direct analog of powerful, high-redshift, radio galaxies that are known to have large quantities of galaxy-scale cold gas. Our Chandra observation will give us a unique opportunity to spatially resolve the jet-gas feedback process in action.
