Contexte de travail

The Centre National de la Recherche Scientifique (CNRS) is a major player in fundamental research on a global scale. The CNRS is divided into 17 delegations, including the Ile-de-France Gif-sur-Yvette delegation. As part of this delegation, the Laboratory for the Use of Intense Lasers (LULI) is based on the École Polytechnique campus, but is also present on the Orme des Merisiers site and at Jussieu.

At the LULI laboratory, we have two large laser installations: LULI2000 and Apollon on which large-scale experiments are carried out to meet astrophysical challenges. In addition, we have developed an external high magnetic field platform capable of delivering 30T (60T in the near future) in a large volume (1 cm3). The coupling between the high-power laser and the external B field opens a new domain in laboratory astrophysics: magnetized plasmas. Our post-doctoral position is in this context, tackling one of the most energetic phenomena in the Universe: the explosion of stars. Several questions concerning the interaction of SNR with surrounding environments (circumstellar medium, other SNR, molecular clouds) and magnetic fields (B) remain unresolved. In particular, how does field B affect the propagation of SNR in ISM? What is the impact of a B field in the TSF (Star Forming Trigger) process? How does B field affect turbulence (MHD turbulence) and how could it be applied to particle acceleration? In this post-doc position, the candidate will have to solve one of these questions by performing numerical simulations adapted to the dimensioning of future experiments on LULI2000 facilities, LMJ? Omega, NIF, Gekko
To do this, he/her will perform numerical simulations using the FLASH code (2D/3D MHD radiative code) available in our group to design and interpret the experimental results. If necessary, the applicant will enhance existing models implemented in FLASH and use them to run a large-scale astrophysical simulation that can be directly compared with astronomical observations.
The position is located in a sector covered by the protection of scientific and technical potential (PPST), and therefore requires, in accordance with the regulations, that your arrival be authorised by the competent authority.

Contraintes et risques

The position will take place in the LULI laboratory at the École Polytechnique
Travel in partner laboratories or during conferences/workshop/experiments in France and abroad will be expected.
