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...

Recent observations reveal that cosmic rays (CRs) are more tightly confined in various astrophysical systems (e.g. radio bubbles) than current theories predict. I show that microscale magnetic fluctuations, particularly from the mirror instability...
