- Exploitation of first observations with NectarCAM (2022-2023)


Experience with data-analysis and statistical methods, and a proficiency with Python are desirable. A good command of English, and the ability to work in a team are essential.

Work Context

The gamma-ray astronomy group at Laboratoire Leprince Ringuet (LLR), based at Ecole Polytechnique in the Paris region, has an opening for a postdoctoral fellow to work on the CTA experiment, a state-of-the-art facility that will study of the most energetic sources of radiation in the Universe. The group has a long history in ground- and space-based gamma-ray astronomy, having collaborated in the development of the H.E.S.S. cameras and the Fermi calorimeter. LLR scientists are involved in H.E.S.S., CTA and Fermi, studying galactic and extragalactic sources, including pulsars, binaries, active galactic nuclei, and galaxy clusters. Group members have led the development of advanced analysis techniques and calibration algorithms for gamma-ray detectors.
