Lyons Groups of Galaxies : ウィキペディア英語版 | Lyons Groups of Galaxies Lyons Groups of Galaxies (or LGG) is an astronomical catalog of nearby groups of galaxies complete to a limiting apparent magnitude B0=14.0 with a recession velocity smaller than 5,500 km/s. Two methods were used in group construction: a percolation method derived from Huchra and Geller and a hierarchical method initiated by R. Brent Tully. The catalog is a synthesized version of the two results. The LGG includes 485 groups and 3,933 member galaxies. == See also ==
