Atomic Gas in the Arp 295 Group

A composite image of the optical light (green and yellow), star forming regions (pinkish white), and cold atomic hydrogen gas (blue) in the classic bridge-tail system Arp 295. The atomic hydrogen observations, taken with the VLA in its C and D-array configurations, discovered 9 previously unknown group members (eight of which are seen in this image; the ninth lies outside the display area). Some of these are labelled in an alternative version of this image.

VLA C+D array observations, with a resolution of 28". Optical image and Continuum subtracted Halpha image, showing warm gas ionized by young, hot stars, were obtained with the KPNO 0.9m telescope in 10/92.
