Abstract

Observations of radio recombination line (H92α) and 8.3-GHz continuum emission from several probable thermal sources in the Galactic Centre HII complex Sgr E have been made using the Very Large Array. Line emission has been detected from seven of these sources, confirming their thermal nature and also locating them in a single kinematical entity moving with ν_LSR ≈ -205 km s^-1. The continuum sources are well resolved by the 8-arcsec beam, and several have complex structure including shells, arcs and cores. One source (G 358.6 + 0.06) has no significant H92α flux, despite its relatively bright continuum and flat spectrum. Further observations will be needed to determine whether or not this interesting source is actually thermal.
