Title: A new DECam deep field covering the full Euclid Deep Field South

Abstract: Deep fields are an essential component of many astronomical surveys, enabling the study of galaxies at higher redshifts and lower luminosities, and providing high signal-to-noise measurements that are used to calibrate wide-area survey components (e.g., detection efficiency and blending effects, object classification, photometric redshifts, and weak lensing shear). The impact of deep fields in survey science is amplified through overlaps with external datasets: multiwavelength imaging, space-based imaging, and spectroscopy. In June 2019, the Euclid Consortium announced the selection of three deep fields for space-based optical and near-IR imaging and spectroscopy, including the Euclid Deep Field South (EDFS; 23~deg$^2$) centered at (RA, Dec) = (61.24, -48.42). EDFS is a candidate Deep Drilling Field (DDF) for the Vera Rubin Observatory Legacy Survey of Space and Time (LSST). Deep multiband imaging of the entire EDFS using the Dark Energy Camera (DECam) extending 1.25 mag deeper than the Dark Energy Survey (DES) would accelerate characterization of this field, enhance the accuracy of photometric redshifts for DES, inform the LSST survey strategy and commissioning efforts, and begin the assembly of a legacy multiwavelength dataset of broad utility to the international astronomical community.
