13 Jul 1998 | | Subject: | astro-ph | | Affiliation: | University of New South Wales), Q.A. Parker (Anglo-Australian Observatory), D. Proust (Observatoire de Meudon), H. Quintana (Universidad Catolica de Chile), E. Slezak (Observatoire de Nice | | Abstract: | We present new radial velocities for 189 galaxies in a 91 sq. deg region of the Shapley supercluster measured with the FLAIR-II spectrograph on the UK Schmidt Telescope. The data reveal two sheets of galaxies linking the major concentrations of the supercluster. The supercluster is not flattened in Declination as was suggested previously and it may be at least 30 percent larger than previously thought with a correspondingly larger contribution to the motion of the Local Group. | | Source: | arXiv, astro-ph/9807118 | | Services: | Forum | Review | PDF | Favorites | |
