The Impact of Galaxy Flybys on Disk Galaxies
Abstract
Fast, one-off interactions, or flybys, between galaxies are surprisingly common and can even out number mergers at low redshift for massive halos. While these interactions are transient and occur well outside a galaxy's disk, they can still significantly impact the galaxy. We present results from collisionless simulations of three co-planar flybys between pure-disk galaxies demonstrating that flybys can both trigger bar formation and spin-up dark matter halos.
