Talk Title: From Stochastic Physics to Cosmological Inference: Weak Lensing and 21-cm Cosmology Abstract: How do unresolved physical structure and instrumental response shape cosmological measurements? Drawing on weak lensing and a differentiable digital twin of the RHINO 21-cm experiment, this talk explores how higher-order correlations, Galactic foregrounds, and instrument modeling connect physics to observables. It also discusses how Bayesian workflows and LLM agents can support the analysis. Host: Laura Newburgh
