VHE gamma-ray detection of FSRQ QSO B1420+326 and modeling of its enhanced broadband state in 2020
V. A. Acciari, S. Ansoldi, L. A. Antonelli +230
Context. QSO B1420+326 is a blazar classified as a Flat Spectrum Radio Quasar (FSRQ). In the beginning of 2020 it underwent an enhanced flux state. An extensive multiwavelength cam…
The Relativistic Jet Orientation and Host Galaxy of the Peculiar Blazar PKS 1413+135
A. C. S. Readhead, V. Ravi, I. Liodakis +26
PKS 1413+135 is one of the most peculiar blazars known. Its strange properties led to the hypothesis almost four decades ago that it is gravitationally lensed by a mass concentrati…
RoboPol: AGN polarimetric monitoring data
D. Blinov, S. Kiehlmann, V. Pavlidou +29
We present uniformly reprocessed and re-calibrated data from the RoboPol programme of optopolarimetric monitoring of active galactic nuclei (AGN), covering observations between 201…
Evidence for periodic accretion-ejection in LSI+61303
M. Massi, M. Chernyakova, A. Kraus +7
The stellar binary system LS I +61303, composed of a compact object in an eccentric orbit around a B0 Ve star, emits from radio up to gamma-ray energies. The orbital modulation of…
Association of IceCube neutrinos with radio sources observed at Owens Valley and Metsähovi Radio Observatories
T. Hovatta, E. Lindfors, S. Kiehlmann +10
Identifying the most likely sources for high-energy neutrino emission has been one of the main topics in high-energy astrophysics ever since the first observation of high-energy ne…
Two Flares with One Shock: the Interesting Case of 3C 454.3
I. Liodakis, D. Blinov, S. G. Jorstad +18
The quasar 3C 454.3 is a blazar known for its rapid and violent outbursts seen across the electromagnetic spectrum. Using gamma-ray, X-ray, multi-band optical, and very long baseli…
An intermittent extreme BL Lac: MWL study of 1ES 2344+514 in an enhanced state
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +215
Extreme High-frequency BL~Lacs (EHBL) feature their synchrotron peak of the broadband spectral energy distribution (SED) at 10\,Hz. The BL~Lac object 1ES~23…
Testing two-component models on very-high-energy gamma-ray emitting BL Lac objects
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +201
Context. It has become evident that one-zone synchrotron self-Compton models are not always adequate for very-high-energy (VHE) gamma-ray emitting blazars. While two-component mode…
A decade of multi-wavelength observations of the TeV blazar 1ES 1215+303: Extreme shift of the synchrotron peak frequency and long-term optical-gamma-ray flux increase
Janeth Valverde, Deirdre Horan, Denis Bernard +86
Blazars are known for their variability on a wide range of timescales at all wavelengths. Most studies of TeV gamma-ray blazars focus on short timescales, especially during flares.…
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…
Patterns in the multi-wavelength behavior of candidate neutrino blazars
A. Franckowiak, S. Garrappa, V. Paliya +8
Motivated by the identification of the blazar TXS 0506+056 as the first promising high-energy neutrino counterpart candidate, we search for additional neutrino blazars candidates a…
