Galaxy Survey Finds Limit of Cosmic Structure Size
DOI: 10.1063/1.2405695
Each of the 106 688 points in this scatter plot of redshift against right ascension (celestial longitude) represents a galaxy. Presented by Gavin Dalton (Oxford) and Karl Glazebrook (Johns Hopkins) at the June meeting of the American Astronomical Society in Rochester, New York, this mapping of two cosmic wedges out to 4 billion light years is by far the most extensive three‐dimensional galaxy survey to date. The plot summarizes the first two years of the Two Degree Field Galaxy Redshift Survey. The 2dFGRS team is a British‐Australian‐US collaboration that plans to have measured a total of 250 000 galactic redshifts by the end of next year.
