The Milky Way Halo Research Group at STScI

Our research group studies the gaseous halo of the Milky Way to better understand the Galactic ecosystem. We focus on multi-wavelength spectroscopy at UV, optical, and radio wavelengths to measure the flows of baryons between the Galactic disk and halo. These flows play a key role in regulating the rate of star formation and provide a close-up case study of the baryon cycle around a star-forming galaxy. Several of our projects are described below.
