Event Details

3D-HST is a 248-orbit spectroscopic survey with the Hubble Space Telescope designed to study galaxy evolution at z>1. Providing the critical third dimension - redshift - via slitless optical and near-IR grism spectra, 3D-HST opens new possibilities for science and discovery in the deep extragalactic fields AEGIS, COSMOS, GOODS-S and UKIDSSUDS. We have combined the grism observations with archival data to create an unique dataset which incorporates > 1000 HST orbits. Dr. Momcheva will present science highlights from the survey. These include tracing the growth of Milky Waylike galaxies since z~2.5, investigating the star formation rates of quiescent galaxies at 0.3 < z < 2.5, a detailed analysis of resolved stellar populations patterns of galaxies and studying the properties of dust in star-forming galaxies at z~1.
