The Neutral Hydrogen Distribution in Spiral and Irregular Galaxies
Published online by Cambridge University Press: 14 August 2015
Abstract
An investigation of several nearby and irregular galaxies shows significant changes in the neutral hydrogen distribution with morphological type. M31, an Sb, has a central hole while M33, an Sc, has relatively a much smaller hole or no hole at all and NGC 6822, an irregular galaxy, is centrally concentrated. The Hii regions in all these morphological types are found in the regions of highest neutral hydrogen density.
