碰撞Ring星系图集和星表

Atlas and Catalog of Collisional Ring Galaxies

Barry F. Madore, Erica Nelson, Kristen Petrillo

摘要:

我们提出了一个目录和成像图集的经典(碰撞)RING星系蒸馏的Arp-Madore地图集的南方特有的Galvanian和协会,并补充了其他已知的RING星系从已发表的文献。星表列出了最初的主天体,汇编了可用的红移,并提供了中心(目标)星系及其最近的伴星的新位置。127碰撞环系统的说明和他们的组件识别。所有的环都已经确定了合理的对撞机;许多都是经径向速度证实的伴星。最后,我们注意到存在一个罕见的子类的环星系的例子是AM 2136-492,双/同心环星系。这些物体是通过数值模拟预测的,但它们在自然界中似乎非常罕见和/或短暂。

英文摘要:

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 sub-class 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.
