Astrophysics

Each week, we hold a relatively informal seminar/discussion series with an emphasis on extra-galactic and large-scale structure astrophysics.

During Galread a leader/visitor presents a recent paper to the discussion group. The PDF of the paper is...

I will present and discuss new analytical solutions to high eccentricity perturbed Keplerian orbits undergoing Kozai-Lidov oscillations. In particular, I will show that the complex dynamics of hierarchical few body stellar systems - can be reduced...

The Bahcall Lunch follow the astrophysics colloquium lecture. Registration is required by noon the previous Thursday so a meal can be provided.

The synthesis of heavy elements in the cosmos has proven to be more complex than originally thought. With advancements in observational astronomy and the addition of new signals from gravitational waves and pre-solar grains, new patterns emerge that...

In the contemporary Universe, most galaxies are supported by ordered rotation, yet a majority of the most massive and quiescent systems are dominated by random stellar motions and classified as slow-rotators. Slow rotators are expected to be rare at...
