A distant elliptical galaxy seen through a foreground spiral *
Received 21 October 1996 / Accepted 7 November 1996
The radio source PKS 0400-181 is a classical edge-brightened radio double, which was tentatively identified with a faint red object thought to be a distant galaxy located behind a spiral galaxy. The properties of the red object were found to be consistent with a giant elliptical galaxy at a redshift of . New spectroscopic observations confirm this interpretation; the measured redshift of the background elliptical is 0.341. This result provides further evidence that, contrary to some previous suggestions, spiral galaxies are not opaque.
