Galaxy Evolution in the Resolved Universe

Colloquium: Astronomy Colloquia | March 5 | 4:10 p.m. | 1 LeConte Hall


Daniel Weisz, University of Washington

Department of Astronomy


The Local Group (LG) is both a foundation and a frontier in our quest to understand the universe. Stellar evolution, the initial mass function (IMF), the extinction law, and the distance scale — all required for interpreting observations of distant galaxies — are anchored in the resolved stellar populations of our neighboring galaxies. These same observations also encode the fossil record of star...   More >

The Increasing Complexity of Exoplanet Atmospheres

Colloquium: Astronomy Colloquia | March 19 | 4:10 p.m. | 1 LeConte Hall


Emily Rauscher, Princeton

Department of Astronomy


While there are now many types of exoplanets that have been discovered, the "hot Jupiter" class remains a focus for observers and theorists alike. This partly because these are inherently interesting objects, completely unlike anything in our solar system, but also because these are the best targets for atmospheric characterization. The atmospheric properties of bright transiting planets are...   More >
