Compact Radio Sources near the Galactic Plane


Astrophys. J. Suppl. 80, 211 (1992)

The results of our extension of the 20cm Galactic plane survey reported by Zoonematkermani and coworkers to Galactic latitudes of +-1.8 deg over the central region of the Milky Way (-10 deg <= l <= 40 deg) are reported. We catalog 1457 new discrete radio sources down to flux densities of <=5 mJy an are 95% complete at 20 mJy. A detailed comparison of all radio sources from our complete survey in this longitude range with the IRAS Point Source Catalog proveds classification for 13% of the objects, including 159 compact HII regions, and nearly 100 planetary nebulae over 70 of which are newly identified. We comment briefly on the identity of the remaining radio sources and on the importance of our 6cm survey, currently underway, in defining the radio source population of the Galaxy. Keywords: HII regions-planetary nebulae: general-radio continuum: galaxies- -surveys
