Molecular gas in high-redshift quiescent galaxies
Cold molecular gas represents the fuel for star formation and plays a key role in galaxy quenching. However, it is observationally challenging to detect CO emission in gas-poor quiescent galaxies, particularly at high redshift. Using deep observations with the NOEMA interferometer, we have detected CO emission in three galaxies that are undergoing quenching at z~1. Additionally, we characterized their stellar populations by fitting models to the combined optical spectroscopy and multi-band photometry.
By comparing the properties of the cold gas to those of the stars, we can place new constraints on the physical processes that drive galaxy quenching.
