Princeton University Galread [Galactic/Extragalactic Reading Group]

The Hough Stream Spotter: A new Method for Detecting Linear Structure in Resolved Stars and Application to the Stellar Halo of M31
Sarah Pearson
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

Superpolynomial Lower Bounds Against Low-Depth Algebraic Circuits I : An overview
11:15am|Simonyi Hall 101 and Remote Access

Every multivariate polynomial P(x_1,...,x_n) can be written as a sum of monomials, i.e. a sum of products of variables and field constants.  In general, the size of such an expression is the number of monomials that have a non-zero coefficient in P...

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

Topic 1: Forward modeling in the era of cosmological surveys Topic 2:Multi-wavelength cluster mass estimation with machine learning
Boryana Hadzhiyska and Digvijay Wadekar
12:30pm|Zoom; IAS, West Seminar Room; PU, Peyton Hall Dome Room

Abstract 1: Upcoming cosmological surveys will measure the large-scale distribution of galaxies at the subpercent level. In order to extract unbiased cosmological data while retaining valuable small-scale information, we need highly accurate models...
