After its launch in 2020, EUCLID space telescope will observe a large number of distant galaxies. However, optical aberrations may induce deformations that prevent accurate measurements of the photometry and the morphology of astrophysical objects. When these aberrations are known, deconvolution methods can numerically "inverse’" those deformation and restore better images. In this context, the project consists in the development of a multi-spectral multi-frame deconvolution algorithm for astrophysical data (large dynamic range, presence of field stars,…). Experiments will be made with real data from last generation instruments (VLT/MUSE, VLT/SHERE,…).
This project is in collaboration with the Astrophysics Laboratory (EPFL).
