Post-doctoral position (M/F) in Cosmology

The COS team at LUTH (located at the Meudon site of Paris Observatory, near Paris) is inviting applications for a 2-year postdoctoral position in numerical cosmology. The selected candidate will play a pivotal role in implementing a (flexible) modified gravity model within the RAMSES cosmological N-body (and hydrodynamical) code. They will conduct a suite of large N-body simulations (on French and European supercomputers), exploring the parameter space and investigating the influence of modified gravity on large-scale structures. Additionally, the candidate will make use of the Magrathea library for relativistic ray tracing (i.e., for the study of weak-lensing and redshift space distortions). Such work is key for the interpretation of ongoing and future surveys such as Euclid, DESI and LSST.

The 2024-2028 ANR project ProGraceRay (PRObing GRAvity at Cosmological scalEs with relativistic RAY-tracing) aims at investigating robust probes of the nature of gravity at cosmological scales thanks to a suite of dedicated large cosmological simulations. The project involves 4 main participating institutes LUTH/Paris Observatory (Meudon), IAP/Sorbonne University (Paris), AIM/CEA (Saclay) and LAM/Aix-Marseille University (Marseille). This job announcement concerns the first postdoctoral position (out of three) about N-body simulations in modified gravity at LUTH.
