The SAGA Project: Satellite Galaxy Populations Around Milky Way-like Galaxies

Tuesday, December 11, 2018 - 4:00pm
Prof. Marla Geha (Yale)

The properties of the Milky Way's satellite galaxies provide critical clues to how galaxies form. However, the number of Milky Way satellites and their properties do not fully agree with well-established cosmological models. The SAGA (Satellites Around Galactic Analogs) survey is a long-term prog

The "N" in "N-body"

Dr. Andrew Benson (Carnegie)

N-body simulations are now the standard approach to studying non- linear structure formation. With ~trillion particle simulations now possible, containing many billions of dark matter halos, measures of key quantities (such as the halo mass function) can be made at extremely high precision.
