Galactic images obtained by Russian space observatory published

MOSCOW. Oct 11 (Interfax-AVN) - The Astro Space Center of the Lebedev Physical Institute of the Russian Academy of Sciences has published new scientific data obtained by the Spectrum-R Russian space observatory, the Federal Space Agency reports.

An international team researching active galactic nuclei has obtained a radio-image of active galaxy 0716+714, the report said.

The first image of active galaxy 0716+714 was received in the 6.2-centimeter wave range by the RadioAstron land-and-space-based interferometer (the Spectrum-R radio-telescope linked with a European array of land-based radio-telescopes).

"Data obtained in a surveillance session of more than 24 hours by about a dozen of the biggest land-based radio-telescopes was used in the analysis," the report said.

The researchers also measured the galactic nucleus parameters, the width of the galaxy stream (about 70 arc-milliseconds or 0.3 parsecs) and other astrophysical characteristics.

Radio interferometry is a complex research sphere, which requires much time for data processing. So, the period between the experiment and the publishing of its results may last from one to several years, the report said.

The Spectrum-R space radio-telescope designed by the Lavochkin Research and Production Center caught the first light coming from Cassiopeia A, is a supernova remnant in the Cassiopeia constellation, on September 27, 2011. The RadioAstron interferometer confirmed its stability and efficiency in each of the four wave ranges, 92, 18, 6 and 1.3 centimeters, in this year's operations.
