The GLOSTAR Galactic plane survey. VI. Radio Source Catalog II: 28d < l < 36d and |b| < 1d, VLA B-configuration
Dzib, S. A. et al. January, 2023We have produced a catalog of a total 3323 compact radio sources in the Galactic plane region. Our classification attempts resulted in 93 H II region candidates, 104 radio stars, and 64 planetary nebulae, while it is suggested that most of the remaining radio sources are extragalactic sources. We investigated the spectral indices of radio sources classified as H II region candidates and found that many have negative values. This may imply that these radio sources represent young stellar objects that are members of the star clusters around the high-mass stars that excite the H II regions, but not these H II regions themselves.

The Population of Compact Radio Sources in M17
Yansa, V.; Masque, J. M.; Dzib, S. A. et al. June 2022A catalog of 194 radio sources of the M17 region based on deep X-band VLA observations. The comparison of M17 with the ONC and NGC 6334D-F leads to a similar luminosity function for the three regions, at least for the more luminous sources. However, the radio sources in M17 are three times more numerous compared to the other regions at a given luminosity and their spatial distribution differs from that of Orion.
