Kinematic Evidence for Superbubbles in I ZW 18: Constraints on the Star Formation History and Chemical Evolution
/ Authors
/ Abstract
We have combined measurements of the kinematics, morphology, and oxygen abundance of the ionized gas in \IZw18, one of the most metal-poor galaxies known, to examine the star formation history and chemical mixing processes.
