Princeton University Galread [Galactic/Extragalactic Reading Group]

The Fundamental Plane in the LEGA-C Survey: unraveling the M/L variations of massive star-forming and quiescent galaxies at z∼0.8
Anna de Graaff
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...

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

Topic 1: Weak lensing: globally optimal estimator and a new probe of the high-redshift Universe Topic 2: Hidden symmetries of black holes and the vanishing of the Love numbers
Abhishek Maniyar and Luca Santoni
12:30pm|Zoom; IAS, Bloomberg Hall, Biology Conference Room

Abstract 1: In recent years, weak lensing of the cosmic microwave background (CMB) has emerged as a powerful tool to probe fundamental physics. The prime target of CMB lensing surveys is the lensing potential, which is reconstructed from observed...

Members’ Colloquium

Fluid equations: regularity and Kolmogorov’s turbulence theory
2:00pm|Simonyi Hall 101 and Remote Access

The regularity theory for the Navier-Stokes equation will be reviewed. Motivations from Kolmogorov’s phenomenological theory of turbulence will be discussed. Rigorous mathematical results are obtained to confirm some of the phenomenologies.

Joint IAS/Princeton University Symplectic Geometry Seminar

Morse-Bott theory on singular analytic spaces and applications to the topology of symplectic four-manifolds
4:00pm|Simonyi Hall 101

We describe two extensions, called the virtual Morse-Bott index and circle-equivariant virtual Morse-Bott index, of the classical Morse-Bott index of a Morse-Bott function on a smooth manifold to the setting of (a) suitably defined analytic...
