Recombination line and continuum observations of the galactic center at 10 GHz.
Abstract
Summary. Radio continuum and H85cc recombination lines have been observed at 10 GHz within 15' of the galactic center source Sgr A. The continuum map has a resolution of 77" and shows new structural details in the radio emission. Sgr A appears to be a core-halo source, as has been shown at lower frequencies. The halo has an angular diameter of 6' and a flux density of . The radial velocities of the H85cc lines are predominantly negative. There is no H85cc line toward G0.16-0.15, which may be a flat spectrum, nonthermal source near the galactic center. Key words: galactic center - H II regions Sagittarius A
