Deep learning for exoplanet detection and characterization by direct imaging at high contrast
Théo Bodrito, Olivier Flasseur, Julien Mairal +3
Exoplanet imaging is a major challenge in astrophysics due to the need for high angular resolution and high contrast. We present a multi-scale statistical model for the nuisance co…

REXPACO ASDI: Joint unmixing and deconvolution of the circumstellar environment by angular and spectral differential imaging
Olivier Flasseur, Loïc Denis, Ãric Thiébaut +1
Angular and spectral differential imaging is an observational technique of choice to investigate the immediate vicinity of stars. The relative angular motion and spectral scaling b…
