Degeneracy and Confidence in Planetary Microlensing
Andy Gould
11:00am|Bloomberg Hall Astrophysics Library
Note: This talk is orthogonal to the one he gave at the symposium "The Variable Universe: A Celebration of Bohdan Paczyski" held at Princeton University this September. So this new talk would be of interest even if people saw the symposium talk...

From Galaxy Clustering to Dark Matter Clustering
Jaiyul Yoo
11:30am|Bloomberg Hall Astrophysics Library
I describe three methods to quantify dark matter clustering, making full use of precision measurements of galaxy clustering and weak lensing from recent galaxy redshift surveys. First, using galaxy clustering measurements on small scales, I infer...

The Metallicities and Physical Conditions in Star-forming Galaxies at High-Redshift
Alice Shapley
11:00am|Bloomberg Hall Astrophysics Library
The abundance of heavy elements in the ISM of star-forming galaxies represents a fundamental metric of the galaxy formation process. This metallicity reflects the gas reprocessed by stars, and the metals returned to the ISM by supernova explosions...
