Description
The Dark Energy Survey (DES) is an optical astronomical imaging survey of one-quarter of the Southern sky. The on-sky operations for the survey were completed in 2019, with observations conducted over the course of 6 years with a 3-square-degree wide-field mosaic camera -- the Dark Energy Camera, or DECam -- installed on the Blanco 4-meter telescope at the Cerro Tololo Interamerican Observatory in the Chilean Andes. The primary scientific goal of the DES is to measure properties of the agent driving the acceleration of the Universe (“Dark Energy”) that was discovered over 20 years ago, but the data have also been useful for studies beyond its primary purpose. In this talk, I discuss DES instrumentation, DES operations, and current DES results.
