4d deconvolutionand demixing for supernovafollow-up
TL;DR: In this article, an inverse problem approach is proposed to jointly solve deconvolution and demixing of sources from 4D (x, y, A,t) astronomical data obtained by observing a supernova and its host galaxy at different epochs.
The polychromatic laser guide star : the elp-oa demonstrator at observatoire de haute provence
R. Foy,M. Chatagnat,D. Dubet,P. Éric,J. Eysseric,Francoise-Claude Foy,T. Fusco,Julien Girard,A. Laloge,A. Le Van Suu,B. Messaoudi,S. Perruchot,Pierre Richaud,Y. Richaud,X. Rondeau,Michel Tallon,Éric Thiébaut,M. Boer +17 more
TL;DR: In this article, the authors report the progress of the first demonstrator of the implementation of this concept, at Observatoire de Haute-Provence 1.52m telescope, including the beam propagation to the lasers room to the mesosphere and the algorithms for tip-tilt measurements.

TL;DR: In this article, the authors explore the potential of this technique for future optical interferometry and also because image reconstruction in the optical using phase referencing techniques has only been performed with limited success.
Proceedings ArticleDOI
Optimal multi-epoch combination of direct imaging observations for improved exoplanet detection
TL;DR: In this article , a new algorithm named PACOME, based on PACO's approach, optimally combines, in a maximum likelihood sense, multi-epoch datasets and improves the detection sensitivity of potential exoplanets by taking into account their orbital motions.
Proceedings ArticleDOI
Reduced wavefront reconstruction mean square error using optimal priors: algebraic analysis and simulations
TL;DR: In this article, the mean square error (MSE) is used to assess the reconstruction quality of adaptive optics systems on the Extremely Large Telescopes (ELT) and the authors investigate the evolution of these two error contributions when the number of parameters to be estimated becomes of the order of 10 4.
