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...

Like most galaxies, the Milky Way harbors a supermassive black hole (SMBH) at its center, surrounded by a stellar cluster. In this densely populated environment, stars frequently collide and interact with one another. I will discuss the outcomes and...

Tidal disruption events — where an unfortunate star is destroyed by a previously quiescent supermassive black hole — offer a unique probe of the low mass end of the supermassive black hole population. Recent observational advances have lead to the...

The study of many-body physics is a defining success of quantum mechanics in the last century. From solids to superconductors to exotic topological phases, we have learned how complex collective behavior emerges from simple microscopic laws. Yet...

Abstract: Gravitational lensing by galaxy clusters has emerged as a powerful tool to probe the standard CDM paradigm of structure formation in the Universe. Despite the remarkable explanatory power of CDM on large scales, tensions with observations...

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