Abstract: Inflation, the theory describing a period of exponential superluminal expansion in the early universe, is both a proposed solution to the large-scale structure we see in our night sky and a mystery of which we have little experimental...

Stellar fluids have a low Prandtl number, which distinguishes them from geophysical fluids by allowing for the existence of turbulence regimes that are diffusive yet non viscous. In this talk I will present recent results demonstrating the existence...

The Bahcall Lunch follows the astrophysics colloquium lecture. 

James Webb Space Telescope (JWST) has opened a new window into the early universe, enabling sensitive, high-resolution images of the near-infrared sky and spectroscopy of faint, distant sources. The JWST Advanced Deep Extragalactic Survey (JADES) is...

Abstract: I will present a case for the striking resemblance between bubbles of anti-de Sitter (AdS) within Minkowski spacetime and black holes. These solutions of Einstein’s equations are motivated by high-energy physics and lack horizons. We will...

Over the next decade, the astronomical community will be deploying a number of instruments that will revolutionize our understanding of the low surface brightness universe. The Nancy Grace Roman Space Telescope, in particular, will combine extreme...
