| Abstract: We propose to map the morphology and extent of the blue horizontal branch in the Galactic bulge, using the globular clusters such as NGC 6522 (that has an EHB) in the BDBS footprint as templates. We seek to determine whether the morphology of the EHB depends on Galactic latitude or longitude, and we propose to match with Gaia and Galex archival data when possible. Saha et al. (2018) argue that a young, massive stellar population of He burning stars may be widespread int he bulge and we propose to use the BDBS u-band photometry to help set limits on such a population. |

The Blanco DECam Bulge Survey (BDBS) is an LSST precursor program to image ~200 sq. deg. of the Galactic bulge from -10 < l < +10 to -10 < b <-2.
BDBS targets the relatively low extinction regions of the Southern Galactic bulge. The Survey is in ugrizY, obtained with DECam,
with the goal of retaining precise photometric calibration even at the bright end.
