Astrophysics Seminar: Why a tiny neutrino particle inspired me to simulate and reconstruct the entire Universe
Adrian Bayer (Flatiron)

April 2, 2025 3:30pm - 5:00pm Massive neutrinos suppress the growth of cosmic structure on small, non-linear scales, making it crucial to go beyond a traditional power spectrum analysis to tighten constraints on their mass.
Condensed and Living Matter Seminars

Condensed, Soft & Living Matter Seminar: Physical approaches to understanding and predicting viral evolution
John Barton (University of Pittsburgh)

April 2, 2025 3:30pm - 5:00pm
How predictable is evolution? This question has inspired biological research for decades, but it remains challenging to address quantitatively. In this talk, I will describe how we adapted methods from statistical…

Rittenhouse Lecture: Measuring Cosmic Sound with the Dark Energy Spectroscopic Instrument
Daniel Eisenstein (Harvard University)

April 9, 2025 3:30pm - 5:00pm
I will describe recent results from the Dark Energy Spectroscopic Instrument (DESI) on the measurement of the cosmic distance scale with the baryon acoustic oscillation (BAO) method and its resulting implications for…

Condensed, Soft & Living Matter Seminar: Light Probes and Structural Color in Dense Complex Media: Lost Between Single and Multiple Scattering
Frank Scheffold (University of Fribourg, Switzerland)

April 15, 2025 2:00pm - 3:00pm
Visible light can be used to probe dense, complex media such as colloidal suspensions or compact sediments. In liquid samples, the temporal fluctuations contain information about the local viscoelastic environment,…
