High-order 3D Voronoi tessellation for identifying Isolated galaxies, Pairs and Triplets
A. Elyiv, O. Melnyk, I. Vavilova
Geometric method based on the high-order 3D Voronoi tessellation is proposed for identifying the single galaxies, pairs and triplets. This approach allows to select small galaxy gr…
The entire-sky catalog of isolated galaxies selected from 2MASS
S. N. Mitronova, I. D. Karachentsev, V. E. Karachentseva +1
We present a first entire-sky catalog of isolated galaxies obtained via systematic automated and visual inspections of extended sources from the Two Micron All-Sky Survey (2MASS).…
Galaxy Triplets of the Local Supercluster. 3. Configuration Properties
O. V. Melnyk, I. B. Vavilova
Configuration properties of observed galaxy triplets are studied with the use of the method of configuration parameters and Agekian-Anosova configuration diagram. Statistically sig…
The Structure of the Local Supercluster of Galaxies Revealed by the Three-Dimensional Voronoi's Tessellation Method
O. V. Melnyk, A. A. Elyiv, I. B. Vavilova
3D Voronoi's tessellation method was first applied to identify groups of galaxies in the structure of a supercluster. The sample under consideration consists of more than 7000 gala…
