Workshop: Kinetic physics of astrophysical plasmas

Europe/Paris
Jussieu

Jussieu

Description

The mechanisms of energy dissipation (magnetic or kinetic) that lead to plasma heating or the generation of suprathermal particles occupy a central place in both the heliospheric plasma community and the high energy astrophysics community.  This workshop aims to bring these two communities together to discuss issues of common interest and to share the knowledge gained, both in terms of the physics studied and the numerical methods used. This workshop will leave plenty of room for discussion and exchange between participants. It will focus on three main topics: reconnection, turbulence and shock waves.

This workshop will take place on the Jussieu campus of Sorbonne Université from June 18 to June 20, 2025. The scientific program will be divided into long, didactic review presentations (45 minutes) and shorter presentations on more specialized topics (30 minutes). The list of invited speakers includes: M. Bugli (IAP), F. Casse (APC), G. Cozzani (LPC2E), S. Galtier (LPP), Y. Genolini (LAPTh), C. Granier (KU Leuven), A. Grassi (LULI), A. Gusdorf (LPENS), P. Hennebelle (CEA), D. Manzini (QMUL), C. Mazelle (IRAP), J. Mehlhaff (IPAG), L. Richard (IRF), A. Vanthieghem (LUX), D. Uzdensky (Oxford U.).

For practical reasons, we will not be able to accommodate more than 50 participants. There will be no registration fee. If you are interested in participating in this event, please contact us: workshop.kpap25@gmail.com
