Formation and evolution of spiral arms in galaxies orbiting a Virgo-like cluster
Published online by Cambridge University Press: 21 March 2017
Abstract
The origin of spiral structure in disks of galaxies remains an open question. One of the theories predicts that two-armed, grand design spiral arms originate from tidal interactions with another body. Using N-body simulations we find that a Milky Way-like galaxy can develop spiral arms due to tidal force from a cluster-size dark matter halo.
