Single conjugate adaptive optics for the ELT instrument METIS
Stefan Hippler, Markus Feldt, Thomas Bertram +7
The ELT is a 39m large, ground-based optical and near- to mid-infrared telescope under construction in the Chilean Atacama desert. Operation is planned to start around the middle o…
STIM map: detection map for exoplanets imaging beyond asymptotic Gaussian residual speckle noise
Benoît Pairet, Faustine Cantalloube, Carlos A. Gomez Gonzalez +2
Direct imaging of exoplanets is a challenging task as it requires to reach a high contrast at very close separation to the star. Today, the main limitation in the high-contrast ima…
Probing the structure and evolution of active galactic nuclei with the ultraviolet polarimeter POLLUX aboard LUVOIR
F. Marin, S. Charlot, D. Hutsemékers +6
The ultraviolet (UV) polarization spectrum of nearby active galactic nuclei (AGN) is poorly known. The Wisconsin Ultraviolet Photo-Polarimeter Experiment and a handful of instrumen…
The Planet Formation Imager
John D. Monnier, Stefan Kraus, Michael J. Ireland +36
The Planet Formation Imager (PFI, www.planetformationimager.org) is a next-generation infrared interferometer array with the primary goal of imaging the active phases of planet for…
Characterizing the atmosphere of Proxima b with a space-based mid-infrared nulling interferometer
D. Defrère, A. Léger, O. Absil +9
Proxima b is our nearest potentially rocky exoplanet and represents a formidable opportunity for exoplanet science and possibly astrobiology. With an angular separation of only 35~…
Hi-5: a potential high-contrast thermal near-infrared imager for the VLTI
D. Defrère, M. Ireland, O. Absil +25
Hi-5 is a high-contrast (or high dynamic range) infrared imager project for the VLTI. Its main goal is to characterize young extra-solar planetary systems and exozodiacal dust arou…
