Colloquium: The Dawn of Gravitational Wave Astronomy at Light-year Wavelengths
Stephen Taylor (Vanderbilt University)
For more than 15 years, NANOGrav and other pulsar-timing array collaborations have been carefully monitoring networks of…
High Energy Theory: Bootstrapping Correlators from dS to LSS
Hayden Lee (Chicago)
The physics of the early universe is reflected in the analytic structure of cosmological correlators. Recent years have seen substantial progress in their study, fueled by a novel theoretical approach. In this new…

High Energy Theory Seminar: Resolution Invariance of Intersection Pairings on Calabi-Yau Manifolds
Patrick Jefferson (Johns Hopkins University)
Studies of string theory compactifications suggest that certain “vertical” homological intersection pairings of Calabi-Yau manifolds are invariant under a large set of birational transformations. In this talk, I will…
Rittenhouse Lecture: An imperfect view of the Universe
Alan Heavens (Imperial College London)
Our most expensive telescopes make exquisite images of the distant Universe, but however good the telescope, the images are flawed. The light has been on a long journey, navigating through the rich array…
