The postdoctoral Fellow will work with prof. Simona Mei on the implementation of algorithms for the joint exploitation of Euclid and Rubin/LSST observations. The position includes both the scientific preparation of the Euclid mission and analysis software development. For the scientific preparation of the Euclid mission, the postdoctoral fellow will perform research aimed at preparing the joint exploitation of the two missions. The software development is aimed at precise photometry and/or photometric redshift measurements.
- Develop the software required for the scientific analysis.
- Test and evaluate code performance and scientific accuracy.
- Validate obtained results.
- Publish resultsin refereed scientific journals.
- Present results at meetings of the French Euclid and/or LSST consortia, and at general meetings of the Euclid, LSST, Simons Observatory and CMC-S4 consortia, when these last two apply.
- Present results at national and international conferences.
Candidates must possess a Ph.D. in astrophysics with specialization in the following areas : galaxies (formation, evolution, photometric redshift), galaxy clusters, and large-scale structure. Experience with scientific computing, statistics and data analysis in the context of cosmology and astrophysics is recommended.
- Experience in astronomical imaging and image analysis
- Experience in statistical data analysis, in image and signal processing, and with associated tools.
- Expertise in programming (Python).
- Good knowledge of Linux operating systems.
- Ability to work in a team.
- Analytical abilities and good communication skills.
- Autonomy in problem solving and ability to adapt to new technologies.
The Astroparticle and Cosmology (APC ; http://apc.u-paris.fr/) laboratory of University Paris Cité seeks applications for a postdoctoral fellowship in the science with large galaxy surveys, with specific emphasis on participation in the European Space Agency's (ESA) Euclid Mission in synergy with the Rubin Observatory Legacy Survey of Space and Time (LSST).
Planned for launch in 2024, the Euclid mission will survey the extragalactic sky from the Earth-Sun Lagrange point 2 with the aim of constraining the properties of dark energy and probing galaxy forrmation and evolution. Rubin will begin operations in 2024, surveying the entire Southern sky over the course of its ten-year survey.
The Euclid and Rubin groups at APC are involved in both the science analysis of the surveys and in the development of the Euclid science ground segment. We are particularly active in galaxy and galaxy cluster science, cross-correlation with the cosmic microwave background (CMB), and weak gravitational lensing, and we are developing novel techniques applying machine learning and artificial intelligence in these areas.
There is a strong synergy between the Euclid, Rubin and CMB efforts.
An experience of 1 or 2 year with astronomical imaging and image analysis, scientific computing, statistics and data analysis in the context of galaxy formatioon and evolution, and cosmology is recommended.
Constraints and risks
Travel in France or abroad is to be expected.
