The astrophysics, relativity, and cosmology (ARC) seminar is a graduate student seminar that discusses significant (often foundational) results of both historical or contemporary research interest which are broadly related to the named fields. It takes place at 4:30 pm on alternating Mondays in 312 Cahill at the California Institute of Technology.
