Post-coronagraphic tip-tilt sensing for vortex phase masks: the QACITS technique
Elsa Huby, Pierre Baudoz, Dimitri Mawet +1
Small inner working angle coronagraphs, like the vortex phase mask, are essential to exploit the full potential of ground-based telescopes in the context of exoplanet detection and…
Optimized focal and pupil plane masks for vortex coronagraphs on telescopes with obstructed apertures
Garreth J. Ruane, Olivier Absil, Elsa Huby +5
We present methods for optimizing pupil and focal plane optical elements that improve the performance of vortex coronagraphs on telescopes with obstructed or segmented apertures. P…
Lyot-plane phase masks for improved high-contrast imaging with a vortex coronagraph
Garreth J. Ruane, Elsa Huby, Olivier Absil +4
The vortex coronagraph is an optical instrument that precisely removes on-axis starlight allowing for high contrast imaging at small angular separation from the star, thereby provi…
Exoplanet science with the LBTI: instrument status and plans
D. Defrère, P. Hinz, A. Skemer +21
The Large Binocular Telescope Interferometer (LBTI) is a strategic instrument of the LBT designed for high-sensitivity, high-contrast, and high-resolution infrared (1.5-13 m) im…
Direct exoplanet detection and characterization using the ANDROMEDA method: Performance on VLT/NaCo data
F. Cantalloube, D. Mouillet, L. M. Mugnier +6
Context. The direct detection of exoplanets with high-contrast imaging requires advanced data processing methods to disentangle potential planetary signals from bright quasi-static…
COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses XV. Assessing the achievability and precision of time-delay measurements
V. Bonvin, M. Tewes, F. Courbin +3
COSMOGRAIL is a long-term photometric monitoring of gravitationally lensed QSOs aimed at implementing Refsdal's time-delay method to measure cosmological parameters, in particular…
