Hercules-Corona Borealis Great Wall

(Her-CrB GW)
(large slab of galaxies discovered in 2013)

The Hercules-Corona Borealis Great Wall (Her-CrB GW) is a galaxy filament discovered in 2013 in the investigation of gamma-ray bursts. The evidence for it is many GRBs from the region, implying the region has a relatively dense population of GRB sources, presumed associated with galaxies. It has a redshift in the range of 1.6-2.1, i.e., 10 billion light-years distant, and is 10 billion light-years in its longer dimension, 7.2 billion light-years wide and 1 billion light-years thick. It displaced the Sloan Great Wall as the largest known structure in the universe. Its size presents scientific questions that promise to influence theories and research.
