Abstract:
Galaxies with polar rings (PRGs) are a unique class of extragalactic
objects. Using these, we can investigate a wide range of problems,
linked to the formation and evolution of galaxies, and we can study
the properties of their dark haloes. The progress that has been made
in the study of PRGs has been constrained by the small number of known
objects of this type. The Polar Ring Catalogue (PRC) by Whitmore et
al. (1990AJ....100.1489W 1990AJ....100.1489W) and their photographic atlas of PRGs and
related objects includes 157 galaxies. At present, there are only
about two dozen kinematically confirmed galaxies in this PRG class,
mostly from the PRC.
We present a new catalogue of PRGs, supplementing the PRC and
significantly increasing the number of known candidate PRGs. The
catalogue is based on the results of the original Galaxy Zoo project.
Within this project, volunteers performed visual classifications of
nearly a million galaxies from the Sloan Digital Sky Survey (SDSS).
Based on the preliminary classifications of the Galaxy Zoo, we viewed
more than 40000 images of the SDSS and selected 275 galaxies to
include in our catalogue.
