The first tests of the space telescope "Radioastron" on its interaction with ground-based radio telescopes have been successfully performed, said Thursday the Astro Space Center (ASC) of the Lebedev Physics Institute, Russian Academy of Sciences (FIAN).
As a land-arm trials included in the three antennas of the Russian system "Quasar", as well as radio telescopes at Evpatoria (Ukraine), in Usuda (Japan), Effelsberg (Germany) and the antenna GBT (USA). At the center of scientific data processing ASC LPI already started looking for the so-called interference lobe — that is, the lines in the spectrum that can determine the similarities and differences in the phase of radio waves. The latter, in turn, enables researchers to identify with what they are dealing with, when receiving radio waves from stars and galaxies.
That this is the main goal of the Russian space telescope — to look into the far reaches of the cosmos and unravel the mystery of the origin and formation of the universe. This unique device will carry out a study of galaxies and quasars in the radio structure and dynamics of the areas directly adjacent to the massive black holes to explore themselves black holes and neutron stars in our galaxy, and more.
The essence of the experiment, taking advantage of the international radio telescope "Radioastron" lies in the fact that the study of one of the radio source in space conducted simultaneously ground and space-based radio telescopes to synchronize their work from a single frequency standard. This achieves a high resolution observations.
Himself "Radioastron" is a space telescope with an antenna diameter of 10 m, which is on board the satellite "Spektr-R". The developer of the scientific equipment is the Astro Space Center of Lebedev Physical Institute.
In addition to the main test was also successfully held the first laser ranging, "Spectrum-R". "Reflected signal substantially free of noise. Error of the measurements does not exceed 10 cm "- told the experts conducting the location of the Institute of Applied Mathematics.
Scientific data processing center ASC LPI started the analysis of the results. The following interferometric test between the Earth and the cosmos will be held in December.
