Permanent position in the field of cosmological simulations of galaxies in the context of Euclid and other cosmological surveys

The Astrophysics Department at CEA Paris-Saclay Institute of research into the fundamental laws of the Universe (IRFU), invites applications for a permanent researcher position to begin before the end of 2025, in the field of cosmological simulations of galaxies in the context of Euclid and other cosmological surveys. The applicant is expected to conduct top-end research projects based on ambitious cosmological simulations and their analysis, in connection with the development of new numerical simulation codes for exascale supercomputers and with the exploitation of large cosmological projects including Euclid as well as other complementary surveys. While the key purpose of this position is to strengthen the scientific outcome of cosmological surveys using simulations, we also seek to strengthen the links between large-scale cosmology (including beyond LCDM), structure formation, and the physics of galaxy formation and galaxy clusters, in relation with various ground- and space-based instruments such as ALMA, JWST, and the E-ELT. Projects on machine learning developments related to simulations are also of interest. The group at Paris-Saclay has extensive experience in using grid-based simulation codes such as the RAMSES code and newer GPU-friendly prototypes but also considers the use of other numerical techniques, and has easy access to top-end facilities at the national and European levels (GENCI, PRACE).

The applicant should hold a PhD degree in astrophysics or related fields and demonstrate a strong experience in the completion of simulation-based cosmological projects and their links with observations. Experience in numerical code development/optimization and in extragalactic astronomical observations are also welcome.

CEA Paris-Saclay is located 20 km south of Paris, France, in the vicinity of various universities and other research centers. The Paris region contains numerous research institutes with whom the DAp collaborates (e.g. IAP, IAS Orsay, Observatory of Paris-Meudon, APC). DAp gathers more than 100 faculty and staff members, 50 postdoctoral fellows, and 30 PhD students. DAp offers a lively and very active research environment of the highest international standards. The research at DAp covers many areas of observational, theoretical, and applied astrophysics. Generous funding for conferences, collaborations, personal equipment and publications is available. The salary for this position is very competitive, and includes excellent health insurance, social security benefits, and family support.
