The Department of Astrophysical Sciences has two divisions, astronomy and plasma physics. The astronomy division offers undergraduate and graduate degrees; the plasma division offers a graduate degree. A vibrant community of faculty, research staff, and students work on a wide range of topics in astronomy and astrophysics. The Department also has an active postdoctoral research program. We have strong links to neighboring groups in the Department of Physics, the Institute for Advanced Study, and the Center for Computational Astrophysics at the Simons Foundation, and we run monthly observing events for the public.
