The eBOSS 3D map of the Universe

extended Baryon Oscillation Spectroscopic Survey ( eBOSS)

“Taken together, detailed analyses of the eBOSS map and the earlier SDSS experiments have now provided the most accurate expansion history measurements over the widest-ever range of cosmic time. These studies allow us to connect all these measurements into a complete story of the expansion of the Universe.”  Will Percival
