Atlas and catalog of collisional ring galaxies. Madore B.F., Nelson E., Petrillo K. <Astrophys. J. Suppl. Ser., 181, 572-604 (2009)> =2009ApJS..181..572M
ADC_Keywords: Galaxies, ring ; Galaxy catalogs ; Radial velocities Keywords: galaxies: interactions - galaxies: luminosity function, mass function galaxies: peculiar Abstract: We present a catalog and imaging atlas of classical (collisional) RING galaxies distilled from the Arp-Madore Atlas of Southern Peculiar Galaxies and Associations and supplemented with other known RING galaxies from the published literature. The catalog lists the original host object, compiles available redshifts, and presents newly determined positions for the central (target) galaxy and its nearest companion(s). 127 collisional RING systems are illustrated and their components identified. All of the RINGS have plausible colliders identified; many are radial-velocity confirmed companions. Finally, we make note of the existence of a rare subclass of RING galaxies exemplified by AM 2136-492, double/concentric RING galaxies. These objects are predicted by numerical simulations, but they appear to be quite rare and/or short lived in nature. Description: All three of the current authors independently inspected and reclassified each of the 500+ Category 6 (Ring Galaxies) in Arp & Madore (1987, Cat. VII/170). Only P-type galaxies (on the FMA classification system) were retained for this study. File Summary:

Note (1): RA and DE positions measured to a precision of 5 arcsec. Note (2): S = the separation of the companion from the nucleus of the ring.
Global Notes: Note (G1): The name of the ring nucleus is composed of the name of the host object followed by ring nucleus (RN) (e.g., AM 0147-350:RN); by way of contrast, companion/colliders are identified by the host object name followed by C1, C2, etc. * In table 1, components of AM 2100-725 are misprinted: AM 2056-392:AN instead of AM 2100-725:AN
