Computer Science/Discrete Mathematics Seminar I

Quantum Mechanics, Semidefinite Programming, and Graph Invariants
Matthew Hastings
11:00am|Simonyi 101 and Remote Access

The central problem of physics and quantum chemistry is to find the ground state energy of some physical system governed by quantum mechanics.  In mathematical terms, this means finding the lowest eigenvalue of some linear operator on a vector space...

Princeton University Galread [Galactic/Extragalactic Reading Group]

Topic 1: The Supersonic Project: Lighting Up the Faint End of the JWST UV Luminosity Function Topic 2: Star clusters in the semi-analytical galaxy formation model "L-Galaxies"
Claire Williams (UCLA) and Nils Hoyer (MPIA)
11:00am|Zoom and Peyton Hall, Grand Central

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...

Princeton University Extrasolar Planet Discussion Group

From Wobbles to Worlds: Exploring the Orbital Landscape of Exoplanet TTVs
Daniel Yahalomi (Columbia)
12:00pm|Zoom and Peyton Dome Rm, Princeton University

Transit timing variations (TTVs) are ubiquitous in exoplanet transit datasets, with Kepler alone containing ~2,000 periodic TTVs. However, these TTVs are often ambiguous from a model selection perspective, as it is difficult to determine the...

Princeton University Gravity Initiative Seminar Series

Forming Truncated Accretion Disks
Gibwa Musoke
12:30pm|Princeton University, Jadwin Hall, Princeton Gravity Initiative, 4th Floor

Abstract: Black hole X-ray binaries and Active Galactic Nuclei transition through a series of accretion states in a well-defined order. During a state transition, the accretion flow changes from a hot geometrically thick accretion flow, emitting a...

PU High Energy Theory Seminar

Fusing Conformal Impurities in Higher Dimensions
Yifan Wang
2:30pm|Jadwin Hall, PCTS Room 407

Abstract: We study the operator algebra of extended conformal defects in more than two spacetime dimensions. Such algebra structure encodes the combined effect of multiple impurities on physical observables at long distances as well as the...

Computer Science/Discrete Mathematics Seminar II

Resolution of the Kohayakawa--Kreuter Conjecture
Raphael Steiner
10:30am|Simonyi Hall 101 and Remote Access

A graph $G$ is said to be Ramsey for a tuple of graphs ($H_1,...,H_r$) if every $r$-coloring of the edges of $G$ contains a monochromatic copy of $H_i$ in color $i$, for some $i$. A fundamental question at the intersection of Ramsey theory and the...

Princeton Center for Heliophysics Seminar

Looking at Plasma Turbulence Through a Microscope: Peering into the Smallest Scales of the Turbulent Cascade with Magnetospheric Multiscale and Beyond
Julia Stawarz
2:00pm|Virtual Meeting

Plasmas throughout the Universe are filled with complex, highly nonlinear turbulent fluctuations that transfer energy from the large driving scales down to the smallest scales where energy can be most efficiently dissipated. In the absence of...

Amateur Astronomers Association of Princeton (AAAP) Monthly Meeting

Studying Supernova Remnants using JWST Imagery
Tea Temim
7:30pm|Peyton Hall & Zoom

Supernova explosions are among the most energetic events in the universe and they play a key role in shaping the energy balance, structure, and chemical content of galaxies. They are responsible for the formation and distribution of heavy elements...

Princeton University Thunch Talk

Intracluster Light in the Core of z~2 Galaxy Proto-clusters
Stephane Werner (Durham University)
12:00pm|Peyton Hall, Grand Central

Intracluster light is thought to originate from stars that were ripped away from their parent galaxies by gravitational tides and galaxy interactions during the build up of the cluster. The stars from such interactions will accumulate over time, so...
