Spiral Galaxies: Thickness

Scientific paper

Using the method proposed by Peng (1988) and analyzing the spiral patterns, the thicknesses of 70 southern spiral galaxies whose images were taken from the Digitized Sky Survey at Xinglong Observational Station of Bejing Observatory were measured. The spiral arms of all these galaxies have been fitted on their images with some logarithmic spiral curves to get optimum inclinations.
