    © Pleiades Publishing, Ltd., 2015. We study the synchrotron component of nonthermal radiation of blazars using the spectral energy distribution (SED). The sample contains a total of 877 blazars, including 423 flat-spectrum ...
  • Udovitskiy R.; Sotnikova Y.; Mingaliev M.; Tsybulev P.; Zhekanis G.; Nizhelskij N. (2016)
    © 2016, Pleiades Publishing, Ltd.We present the automated systemfor estimating the parameters of radio sources observed on all available continuum radiometers (two receiving facilities of secondary mirrors No. 1 and No. 2 ...
  • Mingaliev M.; Sotnikova Y.; Mufakharov T.; Erkenov A.; Udovitskiy R. (2013)
    The results of a comprehensive analysis of continuous radio spectra of a sample of Gigahertz-Peaked Spectrum (GPS) sources are reported. The sources are selected from a flux-density-complete sample (S ν ≥ 200 mJy at 4.8 ...
  • Sotnikova Y.; Mikhailov A.; Mufakharov T.; Mingaliev M.; Bursov N.; Semenova T.; Stolyarov V.; Udovitskiy R.; Kudryashova A.; Erkenov A. (2021)
    We present the radio properties of optically selected quasars with z ≥ 3. The complete sample consists of 102 quasars with a flux density level S1.4 ≥ 100 mJy in a declination range -35° ≤ Dec. ≤ +49°. The observations ...
  • Berlin A.; Parijskij Y.; Nizhelskij N.; Mingaliev M.; Tsybulev P.; Kratov D.; Udovitskiy R.; Smirnov V.; Pylypenko O. (2012)
    The MARS-3 third-generation matrix radiometric system has been developed, manufactured, and is currently being used in observations within the framework of the "Cosmological Gene" program. The system is based on new hardware ...
  • Mingaliev M.; Sotnikova Y.; Torniainen I.; Tornikoski M.; Udovitskiy R. (2012)
    Context. Gigahertz peaked spectrum (GPS) radio sources are a class of extragalactic radio sources characterized by a spectral peak in the gigahertz domain. They are a mixed class of quasars and galaxies. A large proportion ...
  • Mingaliev M.; Sotnikova Y.; Udovitskiy R.; Mufakharov T.; Nieppola E.; Erkenov A. (2014)
    © ESO, 2014. Aims. We present a new catalogue of the RATAN-600 multi-frequency measurements for BL Lac objects. The purpose of this catalogue is to compile the BL Lac multi-frequency data that is acquired with the RATAN-600 ...
  • Mingaliev M.; Sotnikova Y.; Mufakharov T.; Nieppola E.; Tornikoski M.; Tammi J.; Lähteenmäki A.; Udovitskiy R.; Erkenov A. (2017)
    © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim We present the results of 9 years of the blazar observing program at the RATAN-600 radio telescope (2005–2015). The data were obtained at six frequency bands (1.1, 2.3, ...
