Compact Radio Sources near the Galactic Plane
Abstract
The results of our extension of the 20 cm 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 55 mJy and 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 provides classification for 13% of the objects, including 159 compact H II 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 6 cm survey, currently underway, in defining the radio source population of the Galaxy.
