The interplay between galaxy transition and molecular gas in the next generation of radio facilities
The well-known galaxy color bimodality suggests that the paths which galaxies transition from blue, gas-rich spirals to red, gas-poor early-type (elliptical and lenticular) galaxies must be traveled rapidly to explain the dearth of intermediate stage objects. Studying the relationship between the interstellar fuel out of which stars form, and the global changes that galaxies undergo provides a window not only into the paths of transitions that galaxies take, but also how the transition mechanisms can feed back upon the relationship between molecular gas and star formation. I will discuss our results from z=0 transitioning galaxy surveys from CARMA and IRAM, and the ways in which next generation radio telescopes will not only provide detailed insights into the relationship between gas and transition at z=0, but also how this relationship evolves with redshift.
