Princeton University Gravity Initiative Spring Seminar Series

Decay for Massless Vlasov Fields on Schwarzschild Spacetimes - A Hamiltonian Approach
Renato Velozo Ruiz
12:30pm|Jadwin Hall, Princeton Gravity Initiative, 4th Floor

Abstract: In this talk, I will present a Hamiltonian approach to show decay for massless Vlasov fields on the exterior of black hole backgrounds. Vlasov fields are transported along the geodesic flow, and so, the existence of trapped geodesics is an...

Institute for Advanced Study / Princeton University Joint Astrophysics Colloquium

The Dragonfly Project: From Diffuse Galaxies to the Cosmic Web
Pieter van Dokkum
11:00am|Peyton Hall, Auditorium, Princeton University

The Dragonfly project is developing a new class of telescopes optimized for low surface brightness astronomy. Originally designed to test the ΛCDM prediction that galaxies are embedded in extended tidal debris fields, Dragonfly combines the light...

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...

Princeton Center for Heliophysics Seminar

Exploring interplanetary shocks with Solar Orbiter
Andrew Dimmock
2:00pm|Virtual Meeting

Shocks are ubiquitous throughout the universe: around stars, supernova remnants, active galactic nuclei, binary systems, comets, and planets, and are known to be efficient particle accelerators. The workings of collisionless shocks are not fully...

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...

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...

University of Pennsylvania Astrophysics Seminar

Formation and Evolution of Brightest Cluster Galaxies: Nature vs Nurture?
Yen-Ting Lin
3:30pm|U.Penn, David Rittenhouse Laboratory, 4E19

The formation and evolution of brightest cluster galaxies (BCGs), the most massive galaxies in the universe, is not a well-understood issue in astrophysics.  Are BCGs special compared to other cluster member galaxies?  If so, were they born special...
