The bright Magellanic irregular galaxy NGC 4449 was observed during the Astro-2 Space Shuttle mission by the Ultraviolet Imaging Telescope (UIT), which obtained images of a ~40 arc…
Ultraviolet Imaging of the z=0.23 Cluster Abell 2246
Robert H. Cornett, Ben Dorman, Eric P. Smith +8
We present deep ultraviolet observations of a field containing the cluster Abell 2246 (z=0.225) which provide far-ultraviolet (FUV) images of some of the faintest galaxies yet obse…
