Description

The unknown sources of very-high-energy (VHE) astrophysical neutrino are also expected to be sources of VHE gamma rays. With a very large field of view (2 sr), a sky coverage of 2/3 of the sky and an uptime ratio better than 95%, HAWC is an outstanding detector to search for gamma-ray counterparts to neutrino sources. We present two works. In the first, limits of VHE gamma ray emission are presented for a large number of likely astrophysical neutrinos. This is performed with short (1, 2, 10 days) and long (1017 days, HAWC’s data set from November 2014 to December 2017) integration time windows. In the second work, we compare predictions of FIRESONG cosmological simulations of neutrino sources under various evolution scenarios to the observation of HAWC of only 2 sources in the entire extragalactic sky. We find that HAWC can constrain some scenarios, specially for no evolution of neutrino sources that are thin to VHE gamma rays.
