In this gallery are my images of objects that form a subset of edge-on galaxies. Superthin Galaxies have a weak or no central bulge and have a axial ration of 8 to 1 or greater giving them a very flat appearance. The term was introduced in a paper by Goad and Roberts in 1981, and technically they describe these galaxies as also having an under abundance of nitrogen, and having a weak central velocity gradient. Although the Integral Sign galaxy (UGC 3697) has a much stronger central velocity gradient, it is often identified to be member at the limits of the definition of this class. In any event, I find this class of galaxy fascinating with their razor like appearance compared to other edge-on galaxies.
