We develope a method to compute the temperature and density structure along the line of sight by inversion of the differential emission measure (DEM), under the assumptions of stratification and hydrostatic equilibrium. read more →

We present the results of RATAN-600 observations of a sample of strong ( S > 0.5 Jy) flatspectrum sources from the JVAS catalog at 10. ° 5-18° (J2000) declinations in 2015, 2016, and 2017 at the frequencies of 2.3, 4.7, 8.2, 11.2, and 21.7 GHz. We have obtained spectra of all 45 sources and isolated sources with significant variations. read more →

In 2018, we implemented the mode of fast radiometry with a discretization interval from 60 to 490 μs at the 4.7 GHz sensitive radiometer for the first time. read more →

On March 20, 2015 the integrated observations of the solar eclipse were carried out at the RATAN-600 radio telescope at 70 wavelengths simultaneously in the range of 1.65cm to 10cm with the 1% frequency resolution. read more →

The bright radio flares from Cygnus X-3, caused by the massive ejections of matter with velocity close to speed of light accur in the certain "huper-sort" X-ray states. read more →

In the Special Astrophysical Observatory the project is running for the search of distant radio galaxies. The project uses both the RATAN-600 radio telescope and the 6-m BTA optical telescope. read more →
