Description du poste

Position Description

The Laboratoire d’Annecy de Physique Théorique (LAPTh) invites applications for a postdoctoral position in theoretical cosmology within DarkES, a joint ANR–DFG research project co‑led by Dr. Azadeh Moradinezhad (LAPTh) and Prof. Julien Lesgourgues (RWTH Aachen University).

The project aims to develop a robust and efficient framework for probing the nature of dark matter and neutrinos with large‑scale‑structure (LSS) observations. The focus will be on incorporating a broad range of neutrino and dark‑matter models into predictions for the power spectrum and bispectrum of galaxies and intensity maps, with particular emphasis on spectroscopic galaxy surveys, including the ESA Euclid mission, and 21‑cm intensity mapping with the SKA Observatory (SKAO).

The project will generalise analytical methods, in particular the Effective Field Theory of Large‑Scale Structure (EFTofLSS), to include massive neutrinos and non‑standard dark matter. The work will combine theoretical modelling with N-body simulations and forecasts for Euclid and SKAO, with the longer‑term goal of applying the framework to the Euclid spectroscopic galaxy sample.

Qualifications

A PhD focused on cosmology completed by the start date; familiarity with perturbative modelling of biased tracers of LSS; a strong command of analysis of N-body simulation to validate analytic predictions of clustering stats‑itics; and ideally experience with galaxy survey data analysis. Strong programming skills in Python and C are expected.

Supervision and environment

The position will be supervised by Dr. Azadeh Moradinezhad within the Astroparticle and Cosmology group at LAPTh (astrocosmolapth.com). The successful candidate will work closely with the group of Prof. Julien Lesgourgues at RWTH Aachen and the group of Prof. Mathias Garny at the Technical University of Munich, and will have the opportunity to join the Euclid Consortium. Two PhD students will also be involved in the DarkES project, offering opportunities for co‑supervision. The position provides access to CNRS/LAPTh computing resources and travel support, as well as interactions with the broader regional community (e.g. University of Geneva and CERN).

Terms

The appointment is for two years. Salary on the CNRS scale, commensurate with experience, including social security and health coverage. The expected start date is 1 October 2027, with some flexibility.
