      The fourth catalog of active galactic nuclei (AGNs) detected by the Fermi Gamma-ray Space Telescope Large Area Telescope (4LAC) between 2008 August 4 and 2016 August 2 contains $2863$ objects located at high Galactic ...

    • 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 ...
