Article scientists appeared in the journal Nature, but its outline is provided in a press release, University of California at Berkeley, whose staff participated in the work.
In the new work has been studied about 70 thousands of galaxies that had been collected during digital sky survey (SDSS). All the studied objects are located at a distance of 3.5 billion light-years from Earth. This information was used to calculate the dimensionless parameter EG, which characterizes the efficiency of processes of gravitational lending, the growth of galactic structures, as well as the formation of clusters on large cosmological scales.
