Job Description

Missions

The advent of large galaxy surveys such as Euclid poses numerous modeling challenges. The ERC COLIBRI project aims specifically to develop new theoretical and numerical tools to overcome one of these challenges: modeling galaxies within their cosmological environment.

The person hired for this position will specifically study the links between galaxies and their cosmological environment through their morphology and intrinsic alignment.

Activity

This work will be based, on the one hand, on an analysis of Euclid-DR1 data and, on the other hand, on an analysis of numerical simulations developed within the group. On the observational side, the focus will be on studying, in particular, the correlations between galaxy morphology and the cosmic web in the local Universe.

Your Profil

Skills

In addition to this collaborative work, independent research and initiative will be strongly encouraged. Candidates must hold a Ph.D. in physics or astronomy at the time of appointment. We are particularly seeking candidates with strong skills in observational data analysis and
hydrodynamic/cosmological simulations using the RAMSES code, as well as in-depth expertise in cosmology and galaxy formation.

Your Work Environment

The CEA's Department of Astrophysics plays a leading role in several international observation programs (including Euclid) and in major high-performance computing projects (cosmological and galactic simulations, code development). The successful candidate will also benefit from the vibrant scientific community on the Paris-Saclay University campus and in the Paris region.

The contract is for a term of 1 year, with a salary based on experience. Substantial funding will be available for conferences, travel, and equipment.
