Title: The DECam Legacy Survey of the SDSS Equatorial Sky

Abstract: We propose to create a public optical imaging survey to complement the vast spectroscopic database of ~2.5 million extragalactic targets created by the SDSS, SDSS-II and SDSS-III/BOSS surveys and the start of the SDSS-IV/eBOSS survey. Using DECam, we will image 6700 deg^2 of the SDSS/BOSS extragalactic footprint that lies in the region -20 < (delta) < +30^\circ to depths of g=24.7, r=23.9, and z=23.0 AB mag (5-\sigma point-source). The goal is to create a high quality multicolor imaging dataset that will be significantly deeper and have better image quality than SDSS or Pan-STARRS. Our survey will enable transformational studies of the dark and baryonic matter distribution in galaxy halos, focusing on the key issues of feedback and halo growth in the evolution of galaxies and AGN. The data will also be useful for studies of the halo and satellites of the Milky Way. In addition to providing a legacy dataset that will greatly enhance the value of the existing SDSS spectroscopy, our proposed survey will enable target selection within this footprint for the future Dark Energy Spectroscopic Instrument survey, which aims to provide spectra of additional tens of millions of galaxies and QSOs. Given its present and future scientific uses, this survey will % almost certainly be among the highest impact projects if approved by the NOAO Survey Program.
