BARRED MAGELLANIC SPIRALS

Current Collaborators: Moire Prescott (University of Wisconsin)
 

Barred Magellanic Spirals (SBm) are noted for their pronounced asymmetry -- usually a one-arm spiral
pattern emanating from the stellar bar that is offset from the dynamical and photometric center of
the galaxy.  Here's a false-color image of NGC 4618 (a prototypical SBm) taken with the S2KB
imager on the WIYN 3.5m.  We are currently assessing the role interactions play in driving the
apparent lopsidedness in Magellanic spirals
