Abstract:  In this talk, I will present upcoming work studying dynamical solutions, near extremal Reissner—Nordström, of fully coupled Einstein—Maxwell theory with a spherically symmetric neutral scalar field. We prove mathematically that extremal...

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

How and where do black hole mergers form in our Universe? After 10 years of GW science with LIGO/Virgo/Kagra, there still seems to be no direct indication of what the underlying astrophysical formation channels are. I will present ideas and ongoing...

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...
