25 March 2010Speaker: Alice Shapley (UCLA) Title:The ISM in Star-forming Galaxies at z~2-3: Surprising New Insights Abstract:There has been a veritable explosion of surveys of z>1.5 galaxies within the few years. Much of this work has focused on the global properties of distant galaxy populations, rather than the detailed physical properties of individual objects. Indeed, given the faint apparent magnitudes and small angular sizes of typical star-forming galaxies in the distant universe, such detailed studies are challenging. However, aided by gravitational lensing and a wide array of multi-wavelength observations, we present some new results that provide insight into the detailed physical conditions in HII regions of star-forming galaxies at z~2-3, the nature of dust extinction in such systems, and the structure of their large-scale outflows -- all crucial ingredients in models of early star formation and its resulting feedback.
