About this Image

A collection of radio and optical images of NGC 2537 and its companion to the south, IC 2233. NGC 2537 is also known as the peculiar galaxy Arp 6 or, because of its distinctive optical appearance, as the "Bear Claw". Clockwise (from the upper left panel) are the distribution of total atomic hydrogen (HI) shown as both 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 that 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
