Princeton University Astrophysical Sciences Special Seminar

Plasma Turbulence in the Solar Wind
Benjamin Chandran
10:00am|Virtual Meeting

Convective motions on the solar surface launch Alfven waves that propagate out into the interplanetary medium. On their way, the waves become turbulent, and their energy cascades from large wavelengths to small wavelengths. At sufficiently small...

SSSeminar

10:00am|Dilworth Room
The Social Science Seminar meets every Monday for presentations by current scholars that begin at 10:00 a.m. and conclude by 11:45 a.m. This year, the seminars are hybrid in nature, accommodating scholars both remotely and in the Dilworth Room. Due...

Princeton University Galread [Galactic/Extragalactic Reading Group]

Chemical Abundance Properties of M31's Inner Stellar Halo from Resolved Stellar Spectroscopy
Ivanna Escala
11:00am|Virtual Meeting

Each week, we hold a relatively informal seminar/discussion series with an emphasis on extra-galactic and large-scale structure astrophysics.

During Galread a leader/visitor presents a recent paper to the discussion group. The PDF of the paper is...

Computer Science/Discrete Mathematics Seminar I

Rainbow structures, Latin squares & graph decompositions
Benny Sudakov
11:15am|Remote Access - see Zoom link below

A subgraph of an edge-coloured graph is called rainbow if all its edges have distinct colours.  The study of rainbow subgraphs goes back to the work of Euler on Latin squares in the 18th century.  Since then rainbow structures were the focus of...

Princeton University Extrasolar Planet Discussion Group

Inferring Migration Histories of Resonant Planets
Sam Hadden
12:00pm|Virtual Meeting

Exoplanet observations have revealed numerous examples of systems hosting planets residing in mean motion resonances. These dynamical configurations are usually assumed to be the product of past orbital migration due to interactions with a proto...

Princeton University Gravity Initiative Virtual Seminar Series

Horizon-scale Modeling of Black Hole Accretion
Eliot Quataert
12:30pm|Virtual Meeting

Abstract: In this talk, I will provide an overview of theoretical models of black hole accretion aimed primarily at non-specialists. I will focus in particular on efforts to understand the dynamics of, and radiation from, plasma in the near-horizon...

Members’ Seminar

The Value of Errors in Proofs
2:00pm|Simonyi Hall 101 and Remote Access

A few months ago, a group of theoretical computer scientists posted a paper on the Arxiv with the strange-looking title "MIP* = RE", impacting and surprising not only complexity theory but also some areas of math and physics. Specifically, it...

Analysis Seminar

Graph comparison
Anton Petrunin
4:30pm|Remote Access

I will survey results related to graph comparison; graph comparison is a certain type of restriction on a metric spaces which is encoded by a given graph.
