We present high-resolution H41α hydrogen recombination line observations of the 12 (3 pc) region surrounding Sagittarius A* (Sgr A*) at 92 GHz using the Millimeter Array at the Owens Valley Radio Observatory (OVRO) with an angular resolution of 7'' × 3'' and velocity resolution of 13 km s-1. New observations of H31α, H35α, H41α, and H44α lines were obtained using the NRAO 12 m telescope, and their relative line strengths are interpreted in terms of various possible emission mechanisms. These NRAO 12 m measurements are the most extensive recombination line survey of this region to date. These OVRO …
