The High-Altitude Water Cherenkov Observatory (HAWC)

The High-Altitude Water Cherenkov Observatory (HAWC) is a facility designed to observe TeV gamma rays and cosmic rays–markers of the most extreme environments in the known universe like supernova explosions, active galactic nuclei, and gamma-ray bursts.  It is located at an altitude of 4,100 meters, between Pico de Orizaba and the Sierra Negra volcanoes near Puebla, Mexico.  The construction of the HAWC observatory started in 2011 and was inaugurated by Dr. France Córdova, Director of the National Science Foundation (NSF) on March 20, 2015., The HAWC Observatory was built in collaboration between the United States and Mexico, with participation by NSF, the U.S. Department of Energy (DOE), and the Mexican Council for Science and Technology (CONACYT).
