Speckle correction in polychromatic light with the self-coherent camera for the direct detection of exoplanets
Johan Mazoyer, Raphaël Galicher, Pierre Baudoz +1
Direct detection is a very promising field in exoplanet science. It allows the detection of companions with large separation and allows their spectral analysis. A few planets have…
Deformable mirror interferometric analysis for the direct imagery of exoplanets
Johan Mazoyer, Raphaël Galicher, Pierre Baudoz +3
Direct imaging of exoplanet systems requires the use of coronagraphs to reach high contrast levels (10^-8 to 10^-11) at small angular separations (0.1"). However, the performance o…
Theia: Faint objects in motion or the new astrometry frontier
The Theia Collaboration, Celine Boehm, Alberto Krone-Martins +96
In the context of the ESA M5 (medium mission) call we proposed a new satellite mission, Theia, based on relative astrometry and extreme precision to study the motion of very faint…
Structuring metadata for the Cherenkov Telescope Array
Mathieu Servillat, Catherine Boisson, Julien Lefaucheur +3
The landscape of ground-based gamma-ray astronomy is drastically changing with the perspective of the Cherenkov Telescope Array (CTA) composed of more than 100 Cherenkov telescopes…
