Astrophysics

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...

A ubiquitous problem in astronomy is correctly assigning absorption/emission in an image/spectrum to the multiple processes occurring along the line of sight within the field of view. We introduce a method to decompose the images/spectra, with full...

The classical perspective of astrophysical discs models them as being flat, circular and coplanar. However, a wealth of observational evidence has highlighted the ubiquity of warped geometries in a variety of contexts. This has motivated theoretical...

The Exascale Computing Project (ECP) is delivering two exascale systems, Frontier and Aurora, and the applications and software technologies to run on them. Trends in scientific applications and computer architecture during the course of the ECP and...

Lyman-alpha absorption lines are a key diagnostic for the state of diffuse baryons in the intergalactic medium (IGM) and for fundamental cosmological parameters. Light shining from distant active galaxies is absorbed by intergalactic hydrogen clouds...

The Bahcall Lunch follow the astrophysics colloquium lecture. Registration is required by 6pm the previous Thursday so a meal can be provided. Email Amanda at cenker@ias.edu with questions.
