Investigation of Radio Spectra and Long Term Variability of GHz-Peaked-Spectrum Radio Sources and Candidates at RATAN-600 Mingaliev M.G., Sotnikova Y.V. The study of the instantaneous spectra and long-term variability of GHz-Peaked-Spectrum (GPS) sources and candidates are present. ... Many of the sources classified as GPS sources in the literature and thus thought to be non-variable, can exhibit variability and appear unforeseeable bright at high radio frequencies during the Planck observation. ...

... 1994: . For the first time the abundance of iron is determined in gas components of 10 blue compact galaxies. ... Within the "Big Trio" program (BTA - RATAN-600 - VLA) optical identifications of the first and second subsamples (40 objects) from the RATAN-600 "Cold" survey catalogue of radiosources with steep spectra have been finished at the 6-m BTA telescope. ... The distances to nearby galaxies measured with BTA were used to study the velocity field in the Local system of galaxies. ... Archive . ...
