FTP, name this large superstructure just beyond the Great Attractor, a filament of galaxies over 500 million light years long but only 15 million light years thick.
Along with Massimo Ramella, the discoverers of this entity theorized that similar entities could be found using a minimum projected beam size of 12 h Mpc. In plots of angle against velocity, this entity appears across the 10,000 kilometer per second region from nine to sixteen hours. A similar entity to this one was discovered by J. Richard Gott III and Marco Juric of Princeton in 2003, and is named after the Sloan Digital Sky Survey. Centered on the Coma cluster and appearing to terminate at the Hercules supercluster, this structure was discovered in 1989 by Geller and Huchra during the CfA redshift study.
