Abstract: The High Altitude Water Cherenkov (HAWC) Observatory has been fully operational since its inauguration on 20 March 2015. Designed to measure cosmic rays and gamma rays in the very high energy (VHE) range (from 100 GeV to 100 TeV), HAWC observes 2/3 of the entire sky every day. HAWC has a large field of view of ~2 sr and a duty cycle of >95%, making it an ideal instrument to search for both new VHE sources and transient activity in the VHE band. In this talk, I will discuss the results from HAWC's first year of data with the full detector, highlighting several new Galactic sources and demonstrating the capability of HAWC to identify VHE transients. I will also discuss the complementarity between HAWC and other instruments such as IceCube in the context of searching for the sources of the highest energy cosmic rays and neutrinos.
