TeV astrophysics with the HAWC observatory

The High Altitude Water Cherenkov (HAWC) Observatory, located in central Mexico at 4100 m above sea level, is sensitive to gamma rays from 300 GeV to more than 100 TeV and continuously observes a wide field-of-view ($\sim$ 2 sr). With its high energy reach and large area coverage, HAWC is well-suited to perform unbiased surveys of the TeV sky. This had lead to numerous studies: cataloging and classifying TeV gamma-ray sources, setting limits on Dark Matter and the Diffuse Gamma-Ray Background, and investigating galactic and extragalactic extended sources as well as high-energy particle acceleration sites. This presentation will be an overview of HAWC's latest findings on these subjects.
