Tracing the Structure of the Universe with Galaxy Surveys
National Air and Space Museum in Washington, DC
Free, Tickets Required
5:15 PM Lecture
6:30 PM Astronomical observing at the Phoebe Waterman Haas Public Observatory, weather permitting
Studies of galaxy formation and cosmology have exploded in recent years due to the immense data obtained from large galaxy surveys like the Sloan Digital Sky Survey. These data are used to construct three dimensional maps that are complemented by detailed theoretical modeling that often requires massive computer simulations.
Cameron McBride, Postdoctoral Fellow at the Harvard-Smithsonian Center for Astrophysics, will discuss how observational data and theory are combined to better understand fundamental questions in our universe, and will highlight some exciting results from ongoing research.
This lecture is part of the Smithsonian's Stars Lecture Series. Other lectures in the series are scheduled for November 8, December 6, and January 24.
Smithsonian's Stars lectures are suitable for ages 13 and up.

Galaxy redshift surveys, such as the SDSS imaged here, map an incredible dynamic range: from star forming regions within galaxies out to the large-scale distribution of millions of galaxies -- the "cosmic web" of our local Universe. SDSS-III DR12, released in early 2015, represents the completion of million of spectra obtained from several million galaxies within this image.
