    • Multifrequency observations of the candidate neutrino-emitting blazar BZB J0955+3551 

      Paliya, Vaidehi S.; Böttcher, M.; Olmo-García, A.; Domínguez, A.; Gil de Paz, A. (IOP Publishing, 2020)
      The recent spatial and temporal coincidence of the blazar TXS 0506+056 with the IceCube-detected neutrino event IC-170922A has opened up a realm of multimessenger astronomy with blazar jets as a plausible site of cosmic-ray ...

    • New hard-TeV extreme blazars detected with the MAGIC telescopes 

      Acciari, V.A.; Arcaro, C.; Ansoldi, S.; Antonelli, L.A.; Arbet Engels, A. (IOP, 2020)
      Extreme high-frequency-peaked BL Lac objects (EHBLs) are blazars that exhibit extremely energetic synchrotron emission. They also feature nonthermal gamma-ray emission whose peak lies in the very high-energy (VHE, E > 100 ...
