Prolate rotator galaxy

Template:Short description Template:Redirect A prolate rotator galaxy, or spindle galaxy, is an unusual class of galaxy that is cigar-shaped and rotates around its long axis.<ref name="mpia20171012">Template:Cite web</ref> A prolate rotator galaxy is an elliptical galaxy in prolate rotation,<ref name="mpia20171012" /><ref name="newsweek20171013">Template:Cite news</ref> meaning they possess a significant amount of rotation around their major axis. To create a prolate rotator galaxy, two large spiral galaxies must collide at right angles.<ref name="Tsatsi2017">Template:Cite journal</ref> One forms the central bar, the other the disk. The bar then dominates the system.

Template:As of, 20 such galaxies were known. Their existence is also predicted by large-scale cosmological simulations. <ref name="mpia20171012" /><ref name="Ebrova2017">Template:Cite journal</ref>
