A New Collisional Ring Galaxy at z = 0.111: Auriga's Wheel
  We report the serendipitous discovery of a collision ring galaxy, identified
as 2MASX J06470249+4554022, which we have dubbed 'Auriga's Wheel', found in a
SUPRIME-CAM frame as part of a larger Milky Way survey. This peculiar class of
galaxies is the result of a near head-on collision between typically, a late
type and an early type galaxy. Subsequent GMOS-N long-slit spectroscopy has
confirmed both the relative proximity of the components of this interacting
pair and shown it to have a redshift of 0.111. Analysis of the spectroscopy
reveals that the late type galaxy is a LINER class Active Galactic Nuclei while
the early type galaxy is also potentially an AGN candidate, this is very
uncommon amongst known collision ring galaxies. Preliminary modeling of the
ring finds an expansion velocity of ~200 kms^-1 consistent with our
observations, making the collision about 50 Myr old. The ring currently has a
radius of about 10 kpc and a bridge of stars and gas is also visible connecting
the two galaxies.
