Description
The High-Altitude Water Cherenkov (HAWC) observatory, located in Volcán Sierra Negra, México, is designed to detect very high-energy (VHE) gamma rays and has provided continuous sky observations in the range of hundreds of GeV to hundreds of TeV since it began operations in 2015. Over nine years (2015–2024), HAWC has revealed the evolution of the light curve of the blazar Markarian 421 (Mrk 421), including both low- and high-activity states. The primary motivation for this work is the VHE flare detected in 2020, the most intense observed to date for this source with HAWC. This event offers a unique opportunity to study the physical processes that occur during extreme activity states in blazars. In this context, we present a temporal analysis of the spectrum of Mrk 421 during its active states, with particular attention to the characteristics and physical implications of this flare.
