1st Abstract

The High-Altitude Water Cherenkov (HAWC) TeV gamma-ray Observatory is located on the slope of the Sierra Negra volcano in Puebla, Mexico, at 4100 meters above sea level. It began full operation at the end of March 2015, and it consists in 300 water Cherenkov detectors (WCD), covering an area of 22,000 square meters. Each WCD consists in a corrugated metallic cylinder (7.3 meters in diameter and 4.5 meters in height) that provides structural support for a bladder with 200,000 liters of ultra clean water and is instrumented with 4 photomultiplier tubes that detect the Cherenkov radiation produced by charged particles from extended air showers. HAWC has an instantaneous field-of-view of ~2 str, equivalent to 15% of the whole sky and continuous operation (24 hours per day).

HAWC can be considered as the actual more powerful instrument to perform TeV gamma ray astronomy using the water cherenkov technique. With an improved Gamma/Hadron rejection method, HAWC is now studying several gamma-ray emission regions, extreme high-energy cosmic-ray sources, and identifying transient phenomena. HAWC will play a key role on studies of active galaxies, gamma-ray bursts, galactic plane sources, cosmic-ray anisotropies, and soon, because its sensitivity, on supernova remnants, pulsar wind nebulae, and related objects. This contribution will show an overview of the HAWC experiment including its impacting on supernova remnants and related objects on the multimessenger astronomy era.
