Prolate rotator galaxy
Template:Short description Script error: No such module "redirect hatnote". A prolate rotator galaxy, or spindle galaxy, is an unusual class of galaxy that is cigar-shaped and rotates around its long axis.[1] A prolate rotator galaxy is an elliptical galaxy in prolate rotation,[1][2] 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.[3] One forms the central bar, the other the disk. The bar then dominates the system.
since 2017[update]Template:Dated maintenance category (articles)Script error: No such module "Check for unknown parameters"., 20 such galaxies were known. Their existence is also predicted by large-scale cosmological simulations. [1][4]
