Title: A Deep Synoptic Study of the Galactic Bulge

Abstract: We will conduct a deep-wide \it ugriz survey of the Galactic bulge in low extinction (A_V <=3) windows, spacing exposures to optimize detection of RR Lyrae stars. These will be used to obtain a detailed extinction map including 3-d tomography within the bulge, enabling determination of age/metallicity (from color-magnitude/Hess diagrams) and their variance vs position, particularly in the bar. The field selection will be coordinated with OGLE/MACHO archives and the HST Bulge Treasury Program for value added. The observing cadence will also be used to evaluate DECam performance for study of short-duration microlensing events. A backup program will test and initiate a search for distant AGN suitable for reverberation mapping. Many additional studies are possible with these observations: we are committed to post our data with no proprietary period. LSST Data Management are interested in these data to test image processing and transient detection, and we propose to support community access to these products as they become available.
