The CEA-Saclay Institute of Research on the Fundamental laws of the Universe (IRFU) is inviting applications for a postdoctoral position in observational cosmology and cosmological simulations. The position is funded by a national grant, awarded to Nathalie Palanque-Delabrouille and Julien Lesgourgues for their French-German (ANR-DFG) collaborative project: New Implications of Lyman-a Forest for Cosmology. The prime focus of the project is to build upon the group expertise on large scale structures to infer new constraints on dark energy, neutrino masses or the nature of dark matter (warm dark matter, fuzzy dark matter, sterile neutrinos etc). The project will make optimal use of Lyman-a data from BOSS/eBOSS and first DESI data, in addition to dedicated high-resolution hydrodynamic simulations on cosmological scales. Theoretical developments will be addressed through the collaboration with the German partner. The project will also benefit from other studies led at IRFU, such as baryon acoustic oscillations, redshift-space distortions, cross-correlations between large-scale structures and other probes (SZ signal from Planck, gravitational lensing), tests of modified gravity.
The candidate will join a dynamic team highly involved in eBOSS and DESI, with strong connexions to optical (DES, CFIS), CMB (Planck) and SZ (Planck clusters) surveys. He/she will be encouraged to take responsibilities and to bring his/her own ideas to the project. The large-scale structure group includes 9 researchers, 7 PhD students and is currently opening positions for 2 postdocs. The position is funded for 2 years, with a possible 1-year extension. Full funding is available for conferences, travel, personal equipment and publications. Applications should consist of a CV, a list of publications and a brief statement of research interests to be submitted to email@example.com and CYeche@lbl.gov. In addition, applications should arrange for 2 to 3 reference letters to be sent directly to the same address before the deadline. All application material should be received by December 11, 2017. The postdoctoral position is expected to start around September 1st, 2018.
