A catalog of automatically detected ring galaxy candidates in PanSTARSS.

TIMMIS I. and SHAMIR L.

Abstract (from CDS):

We developed and applied a computer analysis method to detect ring galaxy candidates in the first data release of the Panoramic Survey Telescope and Rapid Response System (PanSTARRS). The method works by applying a low-pass filter, followed by dynamic global thresholding, to search for closed regions in the binary mask of each galaxy image. Applying the method to ∼3 x 106 PanSTARRS galaxy images produced a catalog of 185 ring galaxy candidates based on their visual appearance.
