A TeV follow-up survey of active galactic nuclei with the HAWC gamma-ray observatory
Description
Active galactic nuclei (AGN), the most common type of GeV gamma-ray sources, have a preponderant role as extragalactic particle accelerators. Unfortunately our vision of them is limited to the nearby Universe by the process of photon-photon attenuation of very high-energy gamma-rays, which limits the observable distance for a given photon energy coverage. The HAWC gamma-ray observatory, an extensive air shower array in continuous operation in Mexico since 2015, has surveyed 2/3 of the sky at TeV energies with the sensitivity to detect the Crab Nebula in single transits. We present a three year follow-up study of a redshift limited sample of AGN previously detected at GeV energies, performed with a sensitivity down to integrated photon fluxes N(> 0.5TeV) ~ 1e-12 cm-2 s-1.
