Princeton University Survey Science Discussion

Multi-resolution joint analysis of ground and space-based imaging: from improved Rubin/Euclid galaxy catalogs to the study of rare transients
Charlotte Ward
2:00pm|Zoom and Peyton 025

We are entering an exciting decade for survey science, where space-based surveys such as Euclid and ground-based surveys such as LSST and LS4 will provide overlapping imaging datasets across the optical and IR. By jointly analyzing multi-resolution...

Rutgers University Astrophysics Seminar

Unveiling the Intrinsic Mass Step of Type Ia Supernovae
Matthew Grayling
2:00pm|Serin Hall Rm 401W, Rutgers and Zoom

It has long been established that the properties of type Ia supernovae (SNe Ia) depend on their local environment, even after typical standardisation methods. This is typically referred to as the mass step, where SNe Ia in high-mass galaxies are on...

Analysis and Mathematical Physics

Min-Max Construction of Anisotropic Minimal Hypersurfaces
Guido De Philippis
2:30pm|Simonyi Hall 101 and Remote Access

We use the min-max construction to find closed hypersurfaces which are stationary with respect to anisotropic elliptic integrands in any closed n-dimensional manifold . These surfaces are regular outside a closed set of zero n-3 dimension. The...

IAS Amplitudes Group Meeting

Surface Gauge Invariance: Soft Limits and the Transmutation of Gluons into Scalars
Jeffrey Backus
2:30pm|Bloomberg Lecture Hall (IAS)

Abstract: It is well-known that amplitudes in Yang-Mills theory are severely constrained by the requirement of gauge invariance. In this talk, I will explore two aspects of YM amplitudes where (surface) gauge invariance plays a paramount role. First...

Princeton University Dark Cosmos Seminar

When Stars Explode: New Physics in Supernovae
Claudio Andrea Manzari
4:00pm|Jadwin Hall, Joe Henry Room

Abstract: Astrophysical events such as core-collapse supernovae (SN) and neutron star mergers offer unique opportunities to explore physics beyond the Standard Model. In this seminar, I will provide an overview of the mechanisms underlying these...

Special Year Seminar I

Spherical Roots of Spherical Varieties
2:00pm|Simonyi 101

We describe three constructions of spherical roots of spherical varieties via embddings, Borel orbits, and harmonic analysis, and give a hint for why they yield the same results. Then we describe more recent extensions of this theory to arbitrary G...

Special Year Seminar II

Equivariant Rigidity of Richardson Varieties
Anders Buch
10:00am|Simonyi 101

I will show that any Schubert or Richardson variety R in a flag manifold G/P is equivariantly rigid and convex. Equivariantly rigid means that R is uniquely determined by its equivariant cohomology class, and convex means that R contains any torus...
