Atomic Gas in the Shell Galaxy NGC 2865

Description

VLA atomic hydrogen observations of the shell galaxy NGC 2865. The gas is shown as yellow contours on an optical image from the Digital Sky Survey. The main body of the NGC 2865 is typical of early type galaxies, but at fainter light levels the galaxy exhibits a peculiar morphology, with many shells, ripples and loops. The VLA spectral line observations shows gas within the main body of the elliptical, but also distributed in an extended ring around it.
Radio data are VLA B and C-array observations at 20" resolution. HI contours start at a level of 3x10<sup>19</sup> atoms cm<sup>-2</sup>, with successive contours a factor of two higher.
