Polar Ring Galaxies in the Galaxy Zoo
  We report observations of 16 candidate polar ring galaxies (PRGs) identified
by the Galaxy Zoo project in the Sloan Digital Sky Survey (SDSS) database. Deep
images of five galaxies are available in the SDSS Stripe82 database, while to
reach similar depth we observed the remaining galaxies with the 1.8-m Vatican
Advanced Technology Telescope. We derive integrated magnitudes and u-r colours
for the host and ring components and show continuum-subtracted H\alpha+[NII]
images for seven objects. We present a basic morphological and environmental
analysis of the galaxies and discuss their properties in comparison with other
types of early-type galaxies. Follow-up photometric and spectroscopic
observations will allow a kinematic confirmation of the nature of these systems
and a more detailed analysis of their stellar populations.
