About this Image

A collection of radio and optical images of the dwarf spiral galaxy UGC 5391. Clockwise (from the upper left panel) are the distribution of total atomic hydrogen (HI) shown as contours and greyscales; the velocity distribution of the HI contoured upon the total HI map; color-coded HI velocity field (red indicates gas which is moving away from us, blue gas which is moving towards us); and the total HI map contoured upon an optical image from the Digital Sky Survey.

Investigator(s):  E. M. Wilcots and M. K. Prescott
