Rutgers University Astrophysics Seminar

The Interplay of Star Formation and Radiative Feedback across Cosmic Time
Shyam Menon
2:00pm|Serin Hall Rm W330, Rutgers and Zoom

Star formation in galaxies are governed by the complex interplay of several nonlinear physical mechanisms operating in the interstellar medium (ISM). However, in spite of the underlying complexity, there is overwhelming evidence for fundamental...

Joint PU/IAS Number Theory

Squarefree Numbers in Short Intervals
Mayank R. Pandey
4:30pm|Simonyi 101 and Remote Access

We count squarefree numbers in short intervals [X, X+H] for H > X^{1/5 - $\delta$}, where $\delta$ > 0 is some absolute constant. This improves on the exponent 1/5 shown by Filaseta and Trifonov in 1992. 

 

In improving bounds on the number of integers...

Joint IAS/Princeton/Montreal/Paris/Tel-Aviv Symplectic Geometry Zoominar

Strongly Invertible Knots, Khovanov Homotopy, and Localization
Robert Lipshitz
9:15am|Remote Access

Strong inversions are a class of order-2 symmetries of knots in . Building on work of Seidel-Smith, Lidman-Manolescu, Stoffregen-Zhang, and others, we will describe a relationship between the Khovanov homology of a knot with a strong inversion and...

Princeton University Astroplasmas Seminar

Fast magnetic reconnection experiments at the National Ignition Facility: flux annihilation and electron heating
Vicente Valenzuela Villaseca
12:30pm|Dome Room, Peyton Hall or Zoom

Magnetic reconnection is a fundamental plasma process whereby two merging flows with oppositely oriented magnetic fields drive the reconfiguration of the field topology inside a current sheet, which rapidly converts magnetic into kinetic energy. This...

Analysis and Mathematical Physics

Variations on Fefferman's Ball Multiplier Theorem
2:30pm|Simonyi Hall 101 and Remote Access

What happens to an Lp function when one truncates its Fourier transform to a domain? This question is now rather well understood, thanks to famous results by Marcel Riesz and Charles Fefferman, and the answer depends on the domain: if it is a...

Computer Science/Discrete Mathematics Seminar I

Sparsification of Gaussian Processes
Anindya De
11:00am|Simonyi 101 and Remote Access

In this talk, we will show that the supremum of any centered Gaussian process can be approximated to any arbitrary accuracy by a finite dimensional Gaussian process where the dimension of the approximator is just dependent on the target error. As a...

Princeton University Galread [Galactic/Extragalactic Reading Group]

TBA
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...
