Balazs while analyzing data from different gamma-ray and X-ray telescopes, in particular the Swift Spacecraft.
[2] The ring of GRBs lies at a distance of about 2.8 gigaparsecs (9.1 billion light years) from Earth at the redshift between 0.78 and 0.86[2] and measures about 1.72 gigaparsecs (5.6 billion light years) in diameter,[2] making it one of the largest structures known.
[4] In early July 2015, after the discovery of the Hercules–Corona Borealis Great Wall, I. Horvath, J. Hakkila and Z. Bagoly, among others, conducted a further detailed analysis of the spatial distribution of GRBs within the distant universe.
[5] With further tests and analyses of the clustering, they found out that the sample had a higher concentration than the expected normal level, indication of a massive galactic structure within the vicinity.
[2] The authors list the following characteristics for the 9 GRBs in the ring (l and b are standard Sun-referenced galactic coordinates).
