Description
Quenching of star formation is one of the key drivers of galaxy evolution. We use data taken from the ALMaQUEST survey (ALMA-MaNGA QUEnching and STar formation) to study the change of spatially-resolved molecular gas and star formation properties as galaxies move away from the star-forming main sequence towards the passive regime. In particular, we are interested in investigating where and how star formation quenchs in galaxies. For example, it is the amount of molecular gas (fuel) available to form new stars or the efficiency of molecular gas to form stars that control star formation quenching in nearby galaxies. Our results show that star formation quenching can be driven by various mechanisms, both within a galaxy and between different galaxies. The different drivers of star formation quenching imply diverse evolutionary paths of galaxies. This study, as well as the ALMaQUEST survey, marks a new era of research using ALMA and its extraordinary capability for exploring cold gas properties in extreme environments and galaxy evolution.
