Star formation, gas inflow and outflow of distant star-forming galaxies as revealed by chemical evolution
[Abstract]
Gas inflow and outflow are physical processes that control star formation histories of galaxies. Using simple chemical evolution model, we attempt to extract information about star formation and gas flows of star-forming galaxies at redshift z~1.4. We find a correlation between star formation efficiency and stellar mass. Mass-loading factor, or the ratio of outflow rate to star formation rate, inflow rate and outflow rate are only weakly related to stellar mass, probably due to limited mass range of the galaxies. Although there is still uncertainty about constraint of the gas inflow, our results support the idea that gas consumption by star formation and outflow is generally dominated compared with gas acquisition by inflow in star-forming galaxies at z~1.4, and they evolve along the main sequence of star-forming galaxies by increasing star formation efficiency while consuming the gas by star formation activities.
