Parasitic interference in nulling interferometry
Alexis Matter, Denis Defrère, William C. Danchi +2
Nulling interferometry aims to detect faint objects close to bright stars. Its principle is to produce a destructive interference along the line-of-sight so that the stellar flux i…
Laboratory demonstration of a mid-infrared AGPM vector vortex coronagraph
Christian Delacroix, Olivier Absil, Pontus Forsberg +9
Coronagraphy is a powerful technique to achieve high contrast imaging and hence to image faint companions around bright targets. Various concepts have been used in the visible and…
L'-band AGPM vector vortex coronagraph's first light on VLT/NACO: Discovery of a late-type companion at two beamwidths from an F0V star
D. Mawet, O. Absil, C. Delacroix +20
Context. High contrast imaging has thoroughly combed through the limited search space accessible with first-generation ground-based adaptive optics instruments and the Hubble Space…
