Description

The High Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory is a wide-field of view and high-duty cycle detector sensitive to photons of energies between ~0.3 and ~300 TeV. HAWC has been able to detect several sources from extragalactic origin. In this work we present the results of the search of active galactic nuclei from the Third Catalog of Hard Fermi-LAT sources using more than 1500 days of HAWC live data. We also present the detailed spectral analysis at VHE of three selected active galaxies: Markarian 421, Markarian 501 and M87, along with the modeling of their broadband spectral energy distribution.
