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.

The first three observing runs of the LIGO, Virgo, and KAGRA gravitational wave detectors produced a wealth of "firsts," including the first observation of multiple "ringdown" modes from a black hole---the remnant of the first-ever binary black hole...

Abstract: The quantum extremal surface (QES) formula is an important tool for computing entropy in gravity. For a while, the lore was that this formula offers a good approximation whenever the state is sufficiently semiclassical, i.e. well-described...

The third-generation (3G) Gravitational wave (GW) detectors such as the Einstein telescope (ET) or Cosmic Explorer (CE) are expected to detect thousands of GW merger events per year with localization area less than a degree square. This will enable...

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...
