Description

First results on the search for high energy neutrino emission in coincidence with very high energy (E>100 GeV) gamma-ray flares from two bright extragalactic sources, based on the data collected in 2014-2016 by the ANTARES neutrino detector and High Altitude Water Cherenkov (HAWC) gamma-ray observatory, are presented. The ANTARES telescope observes with high duty cycle an instantaneous field of view of 2π. To study variable sources like blazars, it is crucial to achieve unbiased monitoring and an instrument like HAWC is capable of long term and continuous monitoring of the source with nearly 100% duty cycle. Markarian 421 (Mrk 421) and Markarian 501 (Mrk 501) are brightest and closest BL Lac objects known. In contrast to other types of AGNs, characterized by rapid and large-amplitude flux variability. Radio-loud active galactic nuclei with collimated jets aligned to the line of sight, are candidate sources of the observed high energy cosmic rays and of accompanying neutrinos and gamma rays produced in hadronic interactions with the surrounding medium.
