... However these two galaxies are always mentioned as "non-interacting pair" (e.g. RC1 ... 1959): the latter is an interactinggalaxy and the former is not ... B. A. 1959, Atlas and Catalogue of InteractingGalaxies, Part I (Moscow Univ ...
... The inner p olar rings, or disks, in non-interacting spiral galaxies, the first of which was found by us in NGC 2841 (Sil'chenko et al. 1997), are usually nested in the very centers of the galaxies with the large-scale gaseous disks co-planar and co ...
... In this group, Schneider (1985) previously detected a giant (more than 100 kpc in radius) HI ring that probably once interacted with all three above-mentioned galaxies. ...
... intermediate luminosity and constitutes an isolated non-interacting pair with IC 718--a late-type galaxy of similar luminosity ... Meanwhile, IC 719 constitutes an isolated non-interacting pair with IC 718--a late-type galaxy of similar luminosity. ...
... Groups, especially massive ones, often contain hot (X-ray), diffuse gas, which interacts with the cool gas of the galaxies themselves; this interaction is considered to be one reason for the dearth of cool gas in disk galaxies that are members of groups. ...
... The isolated galaxy NGC 1184 shows negligible gradients both in age and abundances. ... In NGC 7332, the member of a non-interacting triplet, and in NGC 1032, isolated, the mean stellar age falls along the radius ...
