"The New Galactic Bulge [OIII] Planetary Nebulae Luminosity Function"
 

The Macquarie/AAO/Strasbourg H-alpha planetary nebula project (MASH; Parker et al. 2006; Miszalski et al. 2008), based on data from the AAO/UKST SuperCosmos Halpha survey of the Southern Galactic Plane (SHS; Parker et al. 2005), has doubled the number of known PNe in the |l| < 5 deg |b| < 5 deg region in the Galactic Bulge. Since this sample represents an unrivaled, essentially co-located PN population at ~8kpc, it provides unprecedented opportunites to define the [OIII] Galactic Bulge Planetary Nebula Lumninosity Function (PNLF), unravel key PNe physical parameters and eludicate inner Galactic structure.  Using the MOSAIC-II camera on the Blanco 4-m at CTIO in June 2008, we observed 57% of Galactic Bulge Bulge PNe to establish accurate fluxes with which to construct a new [OIII] luminosity function.  We anticipate >90% of the total known Bulge sample will have been observed after our final CTIO observing run. The excellent deep data also offers exciting prospects for new PNe discoveries.
