Impact of model parameter degeneracy on leptonic radiation models. The case of blazar multi-wavelength spectra

F. Apel, A. Omeliukh, A. Franckowiak +1

Leptonic one-zone radiation models are commonly used to describe multi-wavelength data and explore the physical properties of high-energy sources, such as active galactic nuclei. H…

Time-dependent modelling of short-term variability in the TeV-blazar VER J0521+211 during the major flare in 2020

MAGIC Collaboration, S. Abe, J. Abhir +228

The BL Lacertae object VER J0521+211 underwent a notable flaring episode in February 2020. A short-term monitoring campaign, led by the MAGIC (Major Atmospheric Gamma Imaging Chere…

On the possible contributions of two nearby blazars to the NGC 4151 neutrino hotspot

Anastasiia Omeliukh, Samuel Barnier, Yoshiyuki Inoue

The origin of the high-energy astrophysical neutrinos discovered by IceCube remains unclear, with both blazars and Seyfert galaxies emerging as potential sources. Recently, the Ice…
