Precise 3D Map of Galaxies Supports Standard Cosmological Model
Washington DC (SPX) Jul 19, 2016
A team of researchers from the collaboration Sloan Digital Sky Survey III (SDSS-III) have presented this week the latest results obtained from the map obtained by the consortium with data collected over the past ten years. The analysis of the data has been carried out by researchers of this collaboration, including a team from the Institute of Cosmos Sciences at the University of Barcelona (ICCUB). The results presented this week are the work of the galaxy group of the Baryon Oscillation Spectrosc ... read more
