The Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST) will constrain our models of the universe through observations of galaxies and galaxy clusters as well as transients such as supernovae and strongly lensed quasars. We analyze...

Accretion-powered X-ray pulsars are neutron stars that accrete matter from a companion star in a binary system, which exhibit fascinating dynamics. The strong magnetic field of the neutron star guides material onto the magnetic poles, which are...

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.

We find ourselves at a pivotal era in the study of cosmology and galaxy formation. The dark energy + cold dark matter (ΛCDM) paradigm is firmly established as the default cosmological model, owing in large part to its incredible success in...

Abstract: In astrophysical fluid dynamics, stars are considered as isolated fluid masses subject to self-gravity. A classical model of a self-gravitating Newtonian star is given by the gravitational Euler- Poisson system, while a relativistic star...

Deep learning (DL) methods have demonstrated great potential for extracting rich non-linear information from cosmological fields, a challenge that traditional summary statistics struggle to address. Most of these DL methods are discriminative models...

The assembly of planetesimals, a key step in the formation of planets, remains riddled with questions. In particular, there is ambiguity regarding the environments in which dust accumulations at the mid-planes of protoplanetary disks become unstable...
