Institute for Advanced Study / Princeton University Joint Astrophysics Colloquium

Probing Dark Energy w/ Galaxy Clusters and Cosmic Shear
Eduardo Rozo
11:00am|Peyton Hall Auditorium

Growth structure probes have long been consider an indispensable tool for the study of dark energy. In this talk, I will present an analysis of the abundance of DES galaxy clusters to argue against the dynamical dark energy interpretation of the...

Rutgers University Astrophysics Seminar

To metallicity and beyond: untangling the chemical properties of galaxies across mass and redshift
Ryan Trainor
11:00am|Serin Hall Rm 330W, Rutgers and Zoom

The chemical evolution of galaxies traces a host of physical processes: the accretion of intergalactic gas, feedback-driven outflows, and nucleosynthesis via stars and supernovae. A major goal of current galaxy surveys is to characterize these...

IAS Phenomenology Lunch and Meet

Information Discussions on Phenomenology and New Theories beyond the Standard Model
12:30pm|Bloomberg Hall Biology Conference Room (1st Floor, Room 113)

This semester, we will be beginning a *very informal* get-together every Monday of people interested in/working on phenomenology and new theories beyond the standard model.  The idea is to discuss over lunch, perhaps meet up around 12.20, grab lunch...

IAS Amplitudes Group Meeting

Scattering Amplitudes and Geometry in Free Surface Hydrodynamics
Nail Ussembayev
2:30pm|Bloomberg Lecture Hall (IAS)

Abstract: We consider the scattering problem of weakly nonlinear gravity waves on the surface of a two-dimensional incompressible fluid of infinite depth. The leading nonlinear dynamics is governed by four-wave interactions; however, a surprising...

Princeton University Dark Cosmos Seminar

Bloodhound Unleashed: Mapping Dark Matter Substructure in the Milky Way
Hyunsu Kong
4:00pm|Jadwin Hall, Joe Henry Room

Abstract: The Lambda-CDM cosmological model predicts a wealth of small-scale structures, including dark matter subhalos residing within more massive halos such as that of our own Milky Way Galaxy. Some of these subhalos may be massive enough to host...

IAS Physics Group Meeting

Lattice Models for U(1) Chern-Simons Theory
Meng Cheng
11:00am|Bloomberg Lecture Hall (IAS)

Abstract: I will present a class of exactly solvable lattice models of bosonic modes on the square lattice that realize chiral topological phases described by U(1)_{2n}​ Chern-Simons theory. The key ingredient is a factorization of the bosonic...

IAS Special Physics Seminar

Superradiant Interactions of the Primordial Cosmic Neutrino Background and Dark Matter
Savas Dimopoulos
2:30pm|Bloomberg Lecture Hall (IAS)

Abstract: Cosmic relics such as the cosmic neutrino background (CνB) are among the most compelling and elusive targets in fundamental physics. With conventional detectors, the interaction rate is so small that a 10-cm sphere of matter would see...

Rutgers University Astrophysics Colloquium

Tracking iron (Fe) in biological systems – disease diagnostics, stem cell engineering, and more
Jongyoon Han
3:30pm|Serin Hall Rm W330, Rutgers and Zoom

Iron (Fe) is the most abundant element on Earth by mass, and all lifeforms on Earth evolved to utilize Fe for critical biochemical functions. Quantitative measurement of biological iron in cells, tissues, and the human body can reveal important...
