Abstract:
We present the results of a deep and uniform narrowband Hα
imaging survey for planetary nebulae (PNs) in the southern Galactic
bulge. In our survey, we have found 56 new PNs and have rediscovered
45 known PNs. We have measured the radial velocities of this uniformly
selected sample and have also remeasured radial velocities for a
subset of 317 PNs from the Acker catalog. Using the COBE/DIRBE 1.25,
2.2, and 3.5µm images, we show that there is a similar longitude
distribution of the PNs and the COBE light in the zone of our deep
survey. Also, we find that the extinction in our surveyed fields is
not severe and that its distribution is fairly uniform. Finally, we
present Hα fluxes for 47 of our 56 newly discovered PNs and
estimate the survey detection limit.
