After a long break caused by the COVID pandemic, Maison de la Simulation (CEA/CNRS/UPS/UVSQ), France is happy to announce ASTRONUM 2023 – the 15th International Conference on Numerical Modeling of Space Plasma Flows in Pasadena, CA, USA, on June 26 – 30, 2023 (Evening registration and Reception held Sunday, June 25).

The conference will cover the following topics:

(1) Advanced numerical methods for space and astrophysical flows;
(2) Large-scale fluid-based, kinetic, and hybrid simulations;
(3) Turbulence and cosmic ray transport; (4) Magnetohydrodynamics
(5) Software packages for modeling and analyzing plasma flows / Visualisation

with the application to

(1) Physics of the Sun-Heliosphere-Magnetosphere; (2) Interstellar medium and star formation;
(3) Cosmology and galaxy formation; (4) Dynamo effect;
(5) Stellar Physics.

The purpose of the conference is to bring together leading experts in applied mathematics, space physics, astrophysics, and geophysics to discuss the application of novel numerical algorithms and petascale paral- lelization strategies to computationally challenging problems.
The conference will be structured around invited, 40-minute keynote and 25-minute regular talks, and a limited number of contributed talks, with the attempt to have no parallel sessions. E-mail inquiries about the meeting should be directed to Nikolai.Pogorelov@uah.edu and Edouard.Audit@cea.fr.
