New galactic bulge PNe
Listed in IVOA Registry (Virtual Observatory)
We observed 64 newly identified galactic bulge planetary nebulae in the radio continuum at 3 and 6 cm with the Australia Telescope Compact Array.
Description
We present their radio images, positions, flux densities, and angular sizes. The survey appears to have detected a larger ratio of more extended planetary nebulae with low surface brightness than in previous surveys.
We calculated their distances according to Van de Steene & Zijlstra (1995A&A...293..541V). We find that most of the new sample is located on the near side around the galactic center and closer in than the previously known bulge PNe. Based on H{alpha} images and spectroscopic data, we calculated the total H{alpha} flux.

We compare this flux value with the radio flux density and derive the extinction. We confirm that the distribution of the extinction values around the galactic center rises toward the center, as expected.
