Near-field Cosmology @ UW

Nora Shipp

Assistant Professor of Astronomy

University of Washington

My group uses stellar streams, the tidal debris of disrupting satellites and star clusters, to study dark matter. By connecting wide-field survey data to cosmological and idealized simulations, we measure the distribution and particle properties of dark matter in the Milky Way.
