Reproducing the large-scale universe from Sloan Digital Sky Survey data

The BOSS survey has scanned the sky measuring the redshifts of more than 1 million galaxies, yielding a three dimensional picture of luminous sources in our universe covering about 4.5 billion years. An international team of astronomers has now reproduced the observed galaxy clustering and determined the uncertainties in the measurement of observed quantities by generating thousands of simulated galaxy catalogues. For the first time, the separation between pairs of galaxies, and the separation b
