21 cm cosmology -- the concept of using radio telescopes to observe the highly redshifted 21 cm line of neutral hydrogen on cosmological scales -- is a field with tremendous scientific potential.   After nearly 20 years of experimental effort...

Abstract: In previous work, Chandrasekaran, Longo, Penington, and Witten (CLPW) constructed an algebra for an observer in a de Sitter static patch. I will discuss how this algebra is affected by gravitational corrections. I will work in the eikonal...

Plasmas exhibit a wide range of behaviors across fluid and kinetic regimes, governing key processes in diverse laboratory, space, and astrophysical environments. Understanding these systems requires numerical models with varying levels of physical...

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...
