Missions

Applications are invited for a two-year postdoctoral position in the Rubin-LSST group at the CNRS LAPP (Laboratoire d'Annecy de Physique des Particules) institute in France.
The Rubin Observatory will be a central instrument for cosmology in the coming decade. Rubin Observatory is a 8-m class telescope being built in Chile, which will perform a photometric survey (called LSST) of the visible sky in six optical bands over the course of ten years. The time window 2022-2024 will be a great opportunity to join the Rubin-LSST project, as this will correspond to the final phase of the commissioning and to the recording of the first on-sky science data with the full camera in 2023.

The LAPP group has long-standing contributions in two main activities: i) computing developments for the Data Release Processing of Rubin and ii) cosmology constraints from galaxy clusters within the Dark Energy Science Collaboration. A new activity focusing on the Rubin focal plane commissioning is ramping up in 2022, in collaboration with other involved IN2P3 groups.

Activities

The successful candidate is expected to work on two complementary activities, allowing them to develop a broad spectrum of relevant expertise for observational cosmology. On one side, the postdoctorant will contribute to the Rubin focal plane commissioning efforts at pixel level: understanding, controlling and improving the focal plane data will be of crucial importance in order to reach the ultimate performance of the camera required for precision cosmology. On the other side, the postdoctorant will have the opportunity to play a key role in the science preparation for the first cosmology constraints from cluster abundances. One particular focus will be the optimization and calibration of the cluster masses, trying to reduce the dominant systematic uncertainties impacting the weak lensing mass reconstruction in Rubin. This work will be carried out in close collaboration with the LPSC group in Grenoble.

Skills

Candidates should have a PhD in astronomy, astrophysics or physics by the date of appointment and no more than two years of post-doctoral experience. Candidates with already existing expertise in cluster cosmology, weak lensing, photometry, optical survey data analysis or image processing are especially encouraged to apply.

Desired work experience: no more than two years of post-doctoral experience.

Applicants must:
- Apply on the CNRS Job Portal https://emploi.cnrs.fr/Offres.aspx : submit a cover letter explaining their interest in the position and a detailed curriculum vitae (containing a description of their research experience with a list of publications highlighting their personal contributions).
- Have referrals to send at least 2 letters of recommendation directly to lapp_administration_rh_secretariat@lapp.in2p3.fr (further information can be obtained from this same email address).

Applications will be accepted until August 30 2022.

Work Context

LAPP is a laboratory of the Institute of Nuclear Physics and Particle Physics (IN2P3), an institute of the National Center for Scientific Research (CNRS), which coordinates programs in these fields. LAPP is a joint research unit (UMR 5814) of the CNRS and the University of Savoie Mont-Blanc (USMB). More than 150 researchers, teacher-researchers, engineers, technicians, administrators, students and foreign visitors work there. The research carried out at LAPP aims to study the physics of elementary particles and their fundamental interactions, as well as to explore their links with the great structures of the Universe. The work of the LAPP teams aims, among other things, to understand the origin of the mass of particles, to unravel the mystery of dark matter or to determine what happened to the anti-matter present in our universe at the time of the Big Bang.

The LAPP Rubin-LSST group is currently composed of five permanent researchers, one postdoctoral researcher, one IT engineer and one short-term IT engineer.

Constraints and risks

Some short trips have to be planned in France and abroad.
