Scientific paper

We have recently imaged the Sgr B2 Main region with the Very Large Array in the BnA configuration in both H52α line and 7 mm continuum emission. This study is part of a larger effort to characterize high frequency recombination lines in ultracompact and hypercompact HII regions in the Galaxy. In particular, these observations supplement lower resolution H52α and matched resolution 7 mm continuum observations of the same region. The current observations detect H52α emission in 13 individual sources in Sgr B2 Main. The previous line observations had lower resolution and detected line emission from only 4 sources in the same region. A number of the newly detected sources have broad recombination line emission, and several of the lines may have peaks at more than one velocity. We discuss a number of individual sources in detail and place them in the context of a developing model of the early evolution of ultracompact HII regions.
