Properties of the Magellanic Type Galaxies
Published online by Cambridge University Press: 12 April 2016
Abstract
Late-type Magellanic spiral galaxies possess high surface brightness stellar bars whose centers are often offset from the photometric and kinematic disk centers derived from stellar and HI distributions. Since these systems represent the transitional stage between the pure disk and irregular galaxies, and because the spiral arm and bar properties of these systems present many unique aspects, an understanding of their properties will benefit our understanding of the physics underlying the Hubble sequence as well as the mechanisms associated with bar formation. I review detailed photometric and kinematic studies of several important SBm galaxies. Statistical studies using large samples drawn from the Third Reference Catalog of Bright Galaxies support the idea that scenarios invoking the formation of offset bars and/or dominant spiral arms through some tidal interaction mechanism might be attractive, since a common trait among the Magellanic spirals appears to be the presence of a physical neighbor.
