Astrophysicists have proved the correctness of Einstein’s

The researchers conducted another successful test of general relativity and the cosmological model based on it.

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.

Astrophysicists specified Hubble constant

The Gravitational lens helped scientists to conduct the most precise measurement to date of the Hubble constant. Article scientists appeared in the journal The Astrophysical Journal, and its outline is given on the site laboratory SLAC, whose staff participated in the work.

In the study of astrophysics studied object B1608 +656, which consists of two galaxies located close to one another. The gravitational field closer to the Earth of a massive object distorts the trajectory of the photons coming from distant galaxies, which leads to the appearance of the effect of the lens (the so-called gravitational lens, or lens Einstein). As a result, the observer sees just four copies of the same object.
