Description

Intense star formation in galaxies results in powerful, galactic-scale outflows of gas. Because stars form from gas, these outflows have a strong effect on the evolution of galaxies, but the intricacies of the process are still unknown. We investigate the connection between galactic outflows and the structure of galaxies using two independent data sets covering a sample of galaxies between 1 < z < 1.5. The Wide Field Camera 3 grism on the Hubble Space Telescope (HST) provides high spatial resolution spectroscopy yielding maps of the extent and strength of star formation, while absorption line spectra from the Keck Telescope at Mauna Kea provide the intensity of and velocity of the outflows. We present the correlations between star formation rate and outflow velocity, and how the outflow properties relate to the structure of the galaxies.
