The Astroparticle and Cosmology laboratory (APC, http://apc.u-paris.fr/) of the University of Paris seeks applications for three postdoctoral or engineer positions with specific emphasis on participation in the European Space Agency’s Euclid space mission and the Rubin Observatory Legacy Survey of Space and Time (LSST). The cosmology group at APC is actively engaged in Euclid and LSST, as well as the next generation CMB experiments (Simons Observatory, LiteBird space mission, CMB-S4). Experience with scientific computing, statistics and data analysis in the context of cosmology and astrophysics is recommended.
One postdoctoral fellow will primarily focus on CMB/galaxy cross-correlation methodology for constraining cosmology with galaxy clusters and large-scale structure, in collaboration with James Bartlett. The fellowship will be offered for 2 years with a nominal start date between November 1st, 2021 and December 15th, 2021. Candidates should apply on the webpage: https://emploi.cnrs.fr/Offres/CDD/UMR7164-NADOKA-008/Default.aspx
Inquires should be sent to James Bartlett ([email protected]).
In the context of LSST and/or Euclid, in collaboration with Simona Mei, we will consider candidates with expertise in one of the following fields of research: (1) the development of Deep Machine Learning networks to estimate photometric redshifts and integrate them to the APC cosmology team’s networks for treating blended galaxies in weak lensing studies, (2) the study of clusters and proto-cluster studies at z>1.5, and (3) the development of a pipeline for Surface Brightness Fluctuation distance measurements in the local Universe with current observations and future LSST and Euclid imaging. The fellowship will be offered for 1.5 years with a nominal start date between November 1st, 2021 and December 1st, 2022. Given the short term of the appointment, we expect the postdoctoral fellow to work 100% on the project discussed between the fellow and the supervisor.
The third postdoctoral or engineer position will focus on the APC responsibilities of processing and validating LSST simulations, and developing software for the LSST and/or the Euclid pipelines (possibilities include the estimation of the galaxy mass function in galaxy clusters, PSF reconstruction in stacked images, photometric redshift estimation) in collaboration with Simona Mei. The fellowship will be offered for 1(+2 depending on funding) year with a nominal start date between November 1st, 2021 and December 1st, 2022. Given the short term of the initial appointment, for the first year we expect the postdoctoral fellow or engineer to work 100% on the project discussed between the fellow and the supervisor.
While both LSST and Euclid are in preparation, we will apply our algorithms to simulations and the recently acquired observations from the UNIONS/CFIS survey (https://www.cosmostat.org/projects/unions-cfis).
Candidates for the second and third postdoctoral positions should send their application with the following elements to Simona Mei ([email protected]):
- Letter of motivation
- For postdoctoral fellows: statement of research interests: past research and planned research, competences and responsibilities
- For engineers: statement of research interests (if that applies), competences and responsibilities
- Have three recommendation letters sent directly to the same address above
