Implications of a Temperature-dependent Initial Mass Function. III. Mass Growth and Quiescence

The stellar initial mass function (IMF) is predicted to depend upon the temperature of gas in star-forming molecular clouds. introduction an additional parameter, $T_{IMF}$ , into photometric template fitting, suggest most galaxies obey IMF top-heavier than Galactic IMF. implications these revised fits on functions, quiescence and turnoff are discussed. At all redshifts highest become quiescent first with decreasing towards present. synchronous across suggests driven by universal mechanisms rather stochastic or environmental processes.
