COLDz: Probing Cosmic Star Formation With Radio Free–Free Emission (2022)
Journal Article

Radio free–free emission is considered to be one of the most reliable tracers of star formation in galaxies. However, as it constitutes the faintest part of the radio spectrum—being roughly an order of magnitude less luminous than radio synchrotron e...
