Princeton University Extrasolar Planet Discussion Group

Cross-Disciplinary Characterization of Exoplanet Atmospheres: Observation, Theory, and Experiment
Jeehyun Yang (JPL)
12:00pm|Zoom and Peyton Dome Rm, Princeton University

With the advent of JWST, the need for detailed chemical and photochemical models of exoplanet atmospheres has increased. Traditionally, building reaction networks required manually tracking species and reactions, a process that is both time...

Institute for Advanced Study/Princeton University Early Universe/Cosmology Lunch Discussion

Impact of primordial magnetic fields on structure formation
Pranjal Ralegankar (SISSA)
12:30pm|IAS, Rubenstein Commons Rm 1 or Peyton Hall, Grand Central

Primordial magnetic fields (PMFs) offer a simple explanation for the origin of galactic magnetic fields as well as of the purportedly detected magnetic fields in cosmic voids. In the talk, I discuss how PMFs' influence on structure formation can...

Amateur Astronomers Association of Princeton (AAAP) Monthly Meeting

Lighting Up the Dark: Where is the Dark Matter?
7:30pm|Peyton Hall & Zoom

Gravitational lensing and other phenomena help to show the distribution of mass within galaxies and throughout the universe, revealing the connection between the dark and bright sides of the Universe. On galactic scales, the observed mass...

Princeton University Galread [Galactic/Extragalactic Reading Group]

TBA
Osase Omoruyi (CfA) and Tirso Marin (LMU)
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...

Special Groups and Dynamics Seminar - Part 1

Spectral Gap of the Laplacian for Random Hyperbolic Surfaces
Nalini Anantharaman
4:00pm|Simonyi 101

Although there are several ways to ''choose a compact hyperbolic surface at random'', putting the Weil-Petersson probability measure on the moduli space of hyperbolic surfaces of a given topology is certainly the most natural. The work of M...
