Description
The cool gaseous halos around galaxies hold some of the keys in understanding feedback and galactic winds. This cool halo gas can be best studied with background quasars, which are very sensitive probes of not only its presence, but also of its kinematics. With a sample of more than 100 galaxy-quasar pairs from the Megaflow survey, I will present the latest constraints on the metal distribution, the kinematics of the cool gas in the circum-galactic medium in relation to the galaxy host properties. We will discuss the impact of our results on our understanding of feedback processes.
