The X-ray nebula around the type 2 Seyfert galaxy NGC 4388

We report on X-ray emission from the type 2 Seyfert galaxy NGC 4388 observed with the Chandra X-ray Observatory. A hard X-ray peak is found at the position of the active nucleus suggested by optical and radio observations. Extended soft X-ray emission correlates well with the ionization cone found in optical-line emission. A large soft X-ray extension is found up to 16 kpc (and possibly 30 kpc) to the north of the galaxy. Photoionized gas with low ionization parameters (log xi less than or equal to 0.4) appears to be the likely explanation for this emission. The same ionized gas clouds could be responsible for the optical [O III] emission. Fe Kalpha line emission from cold material is found to be extended by a few kpc.
