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…

A wiggling filamentary jet at the origin of the blazar multi-wavelength behaviour

C. M. Raiteri, M. Villata, M. I. Carnerero +96

Blazars are beamed active galactic nuclei known for their strong multi-wavelength variability on timescales from years down to minutes. We aim to investigate the suitability of the…

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…

Magnetically Driven Relativistic Jet in the High-Redshift Blazar OH~471

S. Guo, T. An, Y. Liu +15

Context : Understanding the mechanisms that launch and shape powerful relativistic jets from supermassive black holes (SMBHs) in high-redshift active galactic nuclei (AGN) is cruci…

Cluster analysis of the Roma-BZCAT blazars

D. O. Kudryavtsev, Yu. V. Sotnikova, V. A. Stolyarov +5

Based on the collected multiwavelength data, namely in the radio (NVSS, FIRST, RATAN-600), IR (WISE), optical (Pan-STARRS), UV (GALEX), and X-ray (ROSAT, Swift-XRT) ranges, we have…

Radio properties of high-redshift galaxies at

M. Khabibullina, A. Mikhailov, Yu. Sotnikova +6

Study of high-redshift radio galaxies (HzRGs) can shed light on the active galactic nuclei (AGNs) evolution in massive elliptical galaxies. The vast majority of observed high-redsh…

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…
