NBIA Colloquium: Jim Stone

Speaker: Jim Stone (Institute for Advanced Study)

Title: Astrophysical Fluid Dynamics at Exascale

Abstract: The availability of exascale computing resources has enabled numerical modeling of astrophysical fluid dynamics at unprecedented scale, including the most detailed studies of magnetohydrodynamic turbulence and physically realistic models of accretion disks in full general relativity with radiation transport. The implementation of numerical algorithms that achieve these results will first be briefly described. Then results from a diverse range of applications will be presented, including new insights into the structure of radiation-dominated accretion disks, modeling active galactic nuclei feedback in elliptical galaxies, turbulence and cosmic ray transport in the interstellar medium, and binary neutron star mergers.

Brief Bio-sketch: James Stone is a Professor in the School of Natural Sciences at the Institute for Advanced Study (IAS) in Princeton, NJ. He received a PhD in astronomy from the University of Illinois at Urbana-Champaign, and held faculty appointments at the University of Maryland, Cambridge University, and Princeton University before moving to the IAS in 2019.  Stone's research interests are in the use of numerical methods to study the nonlinear and multidimensional fluid dynamics in a diverse range of astrophysical systems, from star and planet formation to accretion flows onto black holes.

Refreshments will be available in Aud. C after the talk.
