Description

The HAWC gamma ray observatory is located at the Sierra Negra Volcano in Puebla, Mexico, at an altitude of 4,100 meters. HAWC is a wide field of view array of 300 water Cherenkov detectors that are continuously surveying ~ 2sr of the sky, operating since March 2015. The large collected data sample allows HAWC to perform an unbiased monitoring of blazars. One of the closest and brightest blazar in the gamma-ray/X-ray sky, Mrk 421, classified as high-synchrotron-peaked BL Lac class, has extensively monitored by the Large Area Telescope on-board the Fermi satellite, and the BAT and XRT instruments of the Swift satellite. In this work, we use more than 3 years of HAWC data together with Swift-XRT data to characterize potential correlations between both bands. This analysis shows that HAWC and Swift-XRT data are correlated even stronger than expected for quasi-simultaneous observations. This result favors the one-zone synchrotron self-Compton model
