Shrinkage MMSE estimators of covariances beyond the zero-mean and stationary variance assumptions
Olivier Flasseur, Eric Thiébaut, Loïc Denis +1
We tackle covariance estimation in low-sample scenarios, employing a structured covariance matrix with shrinkage methods. These involve convexly combining a low-bias/high-variance…
REXPACO ASDI: Joint unmixing and deconvolution of the circumstellar environment by angular and spectral differential imaging
Olivier Flasseur, Loïc Denis, Éric 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…
Assessing the quality of restored images in optical long-baseline interferometry
Nuno Gomes, Paulo J. V. Garcia, Éric Thiébaut
Assessing the quality of aperture synthesis maps is relevant for benchmarking image reconstruction algorithms, for the scientific exploitation of data from optical long-baseline in…
VITRUV - Imaging close environments of stars and galaxies with the VLTI at milli-arcsec resolution
Fabien Malbet, Jean-Philippe Berger, Paulo Garcia +11
The VITRUV project has the objective to deliver milli-arcsecond spectro-images of the environment of compact sources like young stars, active galaxies and evolved stars to the comm…
