VLA 1.3 & 5cm observations of 9 EGOs in the MW

We find statistically-significant correlations between Lradio and Lbol at two physical scales and three frequencies, consistent with thermal emission from ionized jets, but no correlation between L_H2O_ and L_radio_ for our sample. From these data, we conclude that EGOs likely host multiple different centimeter continuum-producing processes simultaneously. Additionally, at our ~1000au resolution, we find that all EGOs except G18.89-0.47 contain 1~2 massive sources based on the presence of CH_3_OH maser groups, which is consistent with our previous work suggesting that these are typical massive protoclusters, in which only one to a few of the young stellar objects are massive.
