Scientific paper

We present chemical abundances of several light, alpha, Fe-peak, and neutron-capture elements in >100 red giant branch (RGB) stars for three separate off-axis bulge fields. The abundances were determined from equivalent width and spectrum synthesis analyses using high resolution (R=18,000), high S/N (70-100) spectra obtained with the Hydra multi-fiber spectrograph on the Blanco 4m telescope at CTIO. We compare our results in these off-axis fields with those along the bulge minor axis. Additionally, the off-axis abundance trends are compared with other Galactic stellar populations and a bulge chemical enrichment model. This material is based upon work supported by the National Science Foundation under award No. AST-1003201 to C.I.J. and award No. AST-0709479 to R.M.R.
