Galactic Astrophysics at TeV: One Year of Observations with HAWC

Abstract:

The High-Altitude Water Cherenkov Gamma Ray Observatory, or HAWC, is joint US/Mexican air shower array designed to observe gamma rays and cosmic rays between 100 GeV and 100 TeV. HAWC is currently the only high-uptime wide-field TeV observatory in operation. The observatory is carrying out an unbiased survey of the Northern Hemisphere, has a robust program to search for flares and other transient sources of gamma rays, and is well suited to observe spatially extended regions of gamma-ray emission and cosmic-ray anisotropy. HAWC recently concluded its first year of data taking with the complete array. The results include not only observations of many known TeV point sources, but also extended emission from Galactic objects like the Geminga supernova remnant. These results have implications for the origins of several astrophysical anomalies observed in the cosmic-ray data, such as the …
