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…
Optical spectroscopy of Blazars for the Cherenkov Telescope Array
P. Goldoni, S. Pita, C. Boisson +14
Context. Blazars are the most numerous class of High Energy (HE; E about 50 MeV - few 100 GeV) and Very High Energy (VHE; E about 100 GeV - 10 TeV) gamma-ray emitters. As of today,…
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…
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…
