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 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…
Baikal-GVD Astrophysical Neutrino Candidate near the Blazar TXS~0506+056
V. M. Aynutdinov, V. A. Allakhverdyan, A. D. Avrorin +71
We report on the observation of a rare neutrino event detected by Baikal-GVD in April 2021. The event GVD210418CA is the highest-energy cascade observed by Baikal-GVD so far from t…
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…
The Baikal-GVD neutrino telescope: search for high-energy cascades
V. A. Allakhverdyan, A. D. Avrorin, A. V. Avrorin +63
Baikal-GVD is a neutrino telescope currently under construction in Lake Baikal. GVD is formed by multi-meganton subarrays (clusters). The design of Baikal-GVD allows one to search…
Flux-density measurements of the high-redshift blazar PSO J047.4478+27.2992 at 4.7 and 8.2 GHz with RATAN-600
T. Mufakharov, A. Mikhailov, Yu. Sotnikova +5
We report the first detection at 4.7 and 8.2 GHz with the RATAN-600 radio telescope of the source PSO J047.4478+27.2992, which has been announced as a blazar at z=6.1. The average…
Multi-wavelength observations of the BL Lac object Fermi J1544-0649: one year after its awakening
P. H. T. Tam, P. S. Pal, Y. D. Cui +15
We report observations of a transient source \fermi\ from radio to \grs. \fermi\ was discovered by the {\it Fermi-LAT} in May 2017. Follow-up {\it Swift-XRT} observations revealed…
Multiwavelength behaviour of the blazar 3C279: decade-long study from -ray to radio
V. M. Larionov, S. G. Jorstad, A. P. Marscher +84
We report the results of decade-long (2008-2018) -ray to 1 GHz radio monitoring of the blazar 3C 279, including GASP/WEBT, and data, as well as polarim…
Investigating the multiwavelength behaviour of the flat spectrum radio quasar CTA 102 during 2013-2017
F. D'Ammando, C. M. Raiteri, M. Villata +94
We present a multiwavelength study of the flat-spectrum radio quasar CTA 102 during 2013-2017. We use radio-to-optical data obtained by the Whole Earth Blazar Telescope, 15 GHz dat…
The observed radio/gamma-ray emission correlation for blazars with the Fermi-LAT and the RATAN-600 data
T. Mufakharov, M. Mingaliev, Yu. Sotnikova +2
We study the correlation between gamma-ray and radio band radiation for 123 blazars, using the Fermi-LAT first source catalog (1FGL) and the RATAN-600 data obtained at the same per…
