Gamma-ray Survey of our Universe

The High Altitude Water Cherenkov (HAWC) Observatory is an all-sky surveying instrument that covers 2/3 of the sky in 24 hours. In addition to providing continuous sky coverage for transient events with a >95% duty cycle, HAWC is also well suited to measure extended and large-scale structures. The array consists of 300 water Cherenkov detectors and is sensitive to extensive air showers triggered by cosmic rays and gamma rays from 100GeV to 100TeV. I will present the results of HAWC's first year of data, highlighting several TeV discoveries among the numerous supernova remnants and pulsar wind nebulae seen in the Galactic plane. I will also discuss HAWC�~@~Ys transient search for active galactic nuclei flares, gamma-ray bursts, and gravitational wave counterparts.
