A broadband outburst of the compact steep-spectrum quasar 3C 138 in 2024-2026
T. V. Mufakharov, Yu. V. Sotnikova, V. V. Vlasyuk +20
After several decades of relative quiescence, the compact steep-spectrum quasar 3C 138 entered an active phase in 2024-2026, exhibiting strong broadband flaring. We investigate its…
Multiwavelength variability of the high-energy neutrino candidate PKS 0735+178 over three decades
T. Mufakharov, Yu. Sotnikova, V. Vlasyuk +12
We present the multiwavelength variability of the BL Lac object PKS 0735+178, associated with the high-energy neutrino event IC211208A. The light curves cover the radio (1-230 GHz)…
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…
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…
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…
VLBI observations of the high-redshift X-ray bright blazar SRGE J170245.3+130104
Yuanqi Liu, Tao An, Shaoguang Guo +8
Aims. The X-ray luminous and radio-loud AGN SRGE J170245.3+130104 discovered at z 5.5 provides unique chances to probe the SMBH growth and evolution with powerful jets in th…
