W49A - B & D Regions

https://www.nrao.edu/archives/plugins/Dropbox/files/W49A-BDregions_hi.jpg

Description

The W49A B and D regions as imaged at 7 mm with the VLA. Insets show the integrated H52alpha radio recombination line flux toward sources B1 and D. A combination of imaging spectroscopy and multi-frequency observations to determine continuum spectral indices can effectively identify the youngest of the UC HII regions in a massive star forming cluster.
