Multiwavelength quasi-periodic variability of the blazar Ton 599
Yu. V. Sotnikova, T. V. Mufakharov, A. E. Volvach +34
During the last 40-50 years, the TeV blazar Ton 599 has systematically experienced major outbursts detected in a wide wavelength range from radio to -rays. In this work, we pres…
Multiwavelength variability of the blazar AO 0235+164
V. V. Vlasyuk, Yu. V. Sotnikova, A. E. Volvach +28
We present a study of the multiwavelength (MW) variability of the blazar AO 0235+164 based on the radio-to--ray data covering a long time period from 1997 to 2023. The radio dat…
High-redshift quasars at : radio variability and MPS/GPS candidates
Yu. Sotnikova, A. Mikhailov, T. Mufakharov +7
We present a study of the radio variability of bright, mJy, high-redshift quasars at on timescales up to 30-40 years. The study involved simultaneous RATA…
Optical and Radio Variability of the Blazar S4 0954+658
V. V. Vlasyuk, Yu. V. Sotnikova, A. E. Volvach +23
We present an optical-to-radio study of the BL Lac object S4 0954+658 observations during 1998-2023. The measurements were obtained with the SAO RAS Zeiss-1000 1-m and AS-500/2 0.5…
The RATAN-600 multi-frequency catalogue of blazars -- BLcat
Yu. Sotnikova, T. Mufakharov, R. Udovitskiy +6
In this paper we present the RATAN-600 multi-frequency catalogue of blazars, an updated version of the BLcat: the RATAN-600 multi-frequency catalogue of BL Lacertae objects. The ma…
Radio Variability and Broad-Band Spectra of Infrared Galaxies with and without OH Megamaser Emission
Yu. V. Sotnikova, T. V. Mufakharov, A. G. Mikhailov +7
We study the radio variability of galaxies with and without sources of hydroxyl (OH) megamaser radiation based on the continuum radio measurements conducted in 2019-2022 with the r…
High-redshift quasars at -- I. Radio spectra
Yu. Sotnikova, A. Mikhailov, T. Mufakharov +7
We present the radio properties of optically selected quasars with . The complete sample consists of 102 quasars with a flux density level mJy in a declina…
Multifrequency study of GHz-peaked spectrum sources
Yu. Sotnikova, T. Mufakharov, E. Majorova +4
Gigahertz-Peaked spectrum (GPS) sources are compact active galactic nuclei, presumably young precursors of bright radio sources. The study of GPS radio properties provides informat…
