ALMA-IMF XIV: Free-Free Templates Derived from H$41\alpha$ and Ionized Gas Content in Fifteen Massive Protoclusters

Roberto Galván-Madrid, Daniel J. Díaz-González, Frédérique Motte +25

We use the H$41\alpha$ recombination line to create templates of the millimeter free-free emission in the ALMA-IMF continuum maps, which allows to separate it from dust emission. This m…
