A complete catalog of stellar mass maps for PHANGS
Abstract
We request IRAC 3.6 and 4.5 um imaging of four galaxies that have been mapped in molecular gas by ALMA as part of its first large program targeting nearby galaxies (PHANGS: Physics at High Angular resolution in Nearby GalaxieS). IRAC provides a uniquely robust view of the stellar mass distribution, which in turn plays a key role in regulating the properties and behavior of the molecular gas. These are the only targets of our ALMA large program without such imaging. A modest investment of Spitzer time will allow us to measure the drivers of molecular cloud and star formation in these targets.
