WebbThe Shapley super-cluster The aim of this work is to give a more complete overview of … WebbWe present the first application of a spherical collapse model to a supercluster of galaxies. Positions and redshifts of ∼ 3000 galaxies in the Shapley Supercluster (SSC) are used to define velocity caustics that limit the gravitationally collapsing structure in its central part.

WebbWe present a new analysis of the kinematics of the Shapley supercluster based on radial velocities for 1087 galaxies in the clusters A3558 (Shapley 8), A3528 (Klemola 21), A3532 (Klemola 22), A3530, A3556 (SC 1321-314), A3559 (CE 1327-292), A3560, A3562, SC 1329-314 and in the intercluster region of the core of the supercluster, of which 367 are … Webb5 maj 2008 · The relationship between X-ray luminosity and gas mass within 3h50 exp -1 Mpc radius found for nearby clusters is used to show that the ratio of the baryon density to the critical density in the ... WebbThis supercluster contains our own galaxy, the Milky Way, as well as about 100,000 other galaxies. The observed attraction suggests a localized concentration of mass millions of times more massive than the Milky Way. ctis seal
