Laboratoire Leprince-Ringuet (LLR)

The gamma-ray astronomy group (Fermi, H.E.S.S., CTA) at Laboratoire Leprince-Ringuet (LLR) invites applications for a 2-year postdoctoral research position devoted to the measurement of gamma-ray polarization with Fermi-LAT data.

The selected candidate will have a leading role in the analysis of the polarization of the Vela pulsar gamma-ray emission, which requires the development of a dedicated data reconstruction and selection. The work will be performed within the Fermi-LAT collaboration.

The Fermi team at LLR has been involved in the reconstruction and selection of the Fermi-LAT data as well as the search of new gamma-ray pulsars. We also have demonstrated an efficient polarimetry of linearly polarized gamma-rays in their conversion to e+e- pairs with the HARPO detector and implemented an exact, five-dimensional, polarized event generator in the GEANT4 simulation toolkit.

We welcome highly motivated applicants with a Ph.D. degree in astroparticle physics or high-energy physics, obtained recently (typically not earlier than two years before starting the position). The candidates are expected to have an experience in data analysis, with programming skills ideally in C++/ROOT.

The starting date can be between June and October 2022. The position is funded by CNRS/IN2P3. The salary is based on the domestic level and it includes health insurance.

Applications should be sent through the CNRS Job Portal (, and include
 - A CV
 - A brief research statement / motivation letter
 - A publication list
 - Up to three reference letters.
Applications will be considered until the position is filled.
