About this Image

A combined optical-radio image of the quasar IRAS 17596+4221 (Z+227-012) and a companion galaxy. The orange areas are the hydrogen gas imaged by the VLA. In the optical image, there is no direct evidence for an interaction between the galaxy hosting the quasar and the companion galaxy. The extensions in the hydrogen gas, however, are a clear indication of disruption resulting from an interaction between the two galaxies.
