Empirical constraints for the magnitude and composition of galactic winds

Zahid, H J; Torrey, Paul; Vogelsberger, Mark; Hernquist, Lars; Kewley, Lisa; Dave, R

Description

Galactic winds are a key physical mechanism for understanding galaxy formation and evolution, yet empirical and theoretical constraints for the character of winds are limited and discrepant. Recent empirical models find that local star-forming galaxies have a deficit of oxygen that scales with galaxy stellar mass. The oxygen deficit provides unique empirical constraints on the magnitude of mass loss, com-position of outflowing material and metal reaccretion onto galaxies. We formulate the...[Show more]
