Post-doctoral research assistant on GRAVITY+ atmospheric simulations and adaptive optics (H/F)

Missions Applications featuring experience in adaptive optics and/or atmospheric simulations are solicited for a post-doctoral fellowship at Paris Observatory/LESIA in collaboration with the GRAVITY+ consortium. The post-doctoral research assistant (PDRA) will simulate the effect of atmospheric turbulence residuals on interferometric observables after adaptive optics (AO) and fringe-tracking (FT) correction, and participate in the integration of the new GRAVITY+ extreme adaptive optics system in Europe and on the Very Large Telescope (VLT) in Chile. He/she will be member of the consortium and be given the opportunity to participate in GRAVITY-wide early science. The successful candidate will be appointed initially for one year, with possibility for a second year on the basis of satisfactory performance.
Activités In the context of GRAVITY-wide, residual atmospheric piston, tip/tilt and higher orders induce performance losses in the interferometric data, due to the cone effect, the isoplanetic angle and the isopistonic angle. The PDRA will study the Strehl and/or contrast losses as a function of reference star distance up to ≈ 30", based on theoretical arguments and numerical simulations to elaborate the calibration plan for such data. For this purpose, the PDRA will have access to experimental on-sky data and interact with other consortium members (MPE Garching – PI institute, University of Cologne) and partners (ESO). In parallel to this study, the PDRA will join the AO system team lead by the IPAG laboratory in Grenoble with experts from LESIA, Lagrange, CRAL (Lyon), MPE and ESO. He/she will participate in the integration of the new AO system on the bench in Nice and on the VLT at Paranal, with ample flexibility for involvement in the various subsystems, in particular the RTC. The PDRA will be a member of the GRAVITY+ collaboration and participate to the preparation and early-use of the wide-field mode of the instrument. The PDRA will be based at LESIA at Paris Observatory. He/she will work primarily together with: - Paris Observatory-PSL/LESIA: Thibaut Paumard, Yann Clénet, Éric Gendron - Grenoble Observatory/IPAG: Jean-Baptiste Le Bouquin - Côte d'Azur Observatory/Lagrange: Florentin Millour, Olivier Lai The PDRA will also collaborate with the members of the GRAVITY+ consortium and ESO.
