The Inter[Stellar+Galactic] Medium Program of Studies (IMPS) at UC Santa Cruz is a research collaboration with focus on the gas in and outside of galaxies in both the local and distant universe. The program brings together cutting-edge observational projects on the Keck, Lick, and Hubble Space Telescope Observatories and theoretical studies of hydrodynamics and radiative transfer with emphasis on large-scale numerical simulations. The group consists of faculty, postdoctoral researchers, PhD students, and undergraduate researchers from the UCSC Physics Department, Astronomy and Astrophysics Department, and the UCO/Lick Observatory. The program also has established collaborations with similar international groups. This website provides an overview of the program, our research interests, publications, data products, and current research opportunities.
