DELVE SURVEY

DELVE combines public archival data with devoted observations to cover the entire high-Galactic-latitude southern sky. DELVE observations started in February 2019, and have collected > 17,000 DECam science exposures as of August 2021. A map of the existing DECam coverage is shown below with darker colored regions indicating more overlapping exposures. Public releases of the DELVE data are available through the NOIRLab Astro Data Lab... The DECam Local Volume Exploration Survey (DELVE) seeks to understand the faintest and most dark-matter-dominated galaxies. DELVE is a deep, multi-component survey to image the entire high-Galactic-latitude southern sky using DECam on the 4-meter Blanco Telescope at Cerro Tololo Interamerican Observatory in Chile. DELVE combines existing archival DECam data (including data from DES, DECaLS, and DeROSITAS) with 126 nights of novel observations to study dwarf galaxies over a wide range of luminosities, from the faintest dwarf spheroidal galaxies around..
