Ground-space interferometer "RadioAstron" continues to explore uncharted territory — to study active galactic nuclei with very high angular resolution. Interferometer successfully registered the cores of galaxies BL Lizards, as well as objects in the constellation Camelopardalis, Cancer, Hydra, and others on the bases of 6 to 11 Earth diameters in the range of 6 and 18 cm for many of these objects estimates give the value of the brightness temperature of about 10 trillion Kelvins (10 to 13 degrees), exceeding the parameters expected by astronomers, it is essential to study the physics of radiation in the cores of galaxies. These findings may in the future make scientists rethink their understanding of the physics of the universe.

According to experts Astro Space Center of Lebedev Physical Institute (FIAN ASC), the outcome of the review of active galactic nuclei, is a catalog of galaxies studied by radio astronomer. An early version of the "Atlas" has already formed the group conducting the review.

  • Quasar 0748 +126, a range of 1.3 cm, the projection base MCT-GBT about 4.3 diameter of the Earth, the signal-to-noise ratio of about 8

In the early part of the scientific program had successfully observing the water maser in the constellation Cepheus. This facility is located at a distance of 720 parsecs from the Sun and contains a cluster of massive young stars and protostars — the so-called "stellar nurseries", which is formed in the vicinity of the maser emission (this type of electromagnetic radiation has a very narrow range and high intensity, so is a convenient object for study ). The signal was obtained between the space radio telescope "Spektr-R" (the main link of the "RadioAstron") and 40-m radio telescope in the ground Yebese (Spain) as part of the interferometric session. The projection of the base ground-space interferometer was a record for the observations of masers value — about 3.5 Earth‘s diameter, which provided an angular resolution of 60 microseconds of arc.
