``Chain'' Galaxies are Edge-on Low Surface Brightness Galaxies

Dalcanton, Julianne J.; Shectman, Stephen A.

Abstract

Deep HST WFPC2 images have revealed a population of very narrow blue galaxies, which Cowie et al. have interpreted as being a new morphological class of intrinsically linear star forming galaxies at z = 0.5--3. We show that the same population exists in large numbers at low redshifts (z ~ 0.03) and are actually the edge-on manifestation of low surface brightness disk galaxies.
