Mid-IR Water-Vapor Seeing: Implications for ELT/METIS High-Contrast Imaging from VLTI Data

Abhirami S Raghu, Prashant Pathak, Olivier Absil +7

Direct imaging and characterization of rocky exoplanets remains one of the central challenges in exoplanetary science. The mid-infrared (mid-IR) offers a favorable high-contrast im…

METIS high-contrast imaging simulations: From instrument modelling to science readiness

Gilles Orban de Xivry, Olivier Absil, Iain Hammond +9

The Mid-infrared Extremely Large Telescope (ELT) Imager and Spectrograph (METIS) instrument, expected to see first light in early 2030, aims to detect and characterise exoplanets a…

Maximising the mid-infrared high-contrast performance of ELT/METIS despite water vapour seeing

Olivier Absil, Gilles Orban de Xivry, Prashant Pathak +7

The Mid-infrared ELT Imager and Spectrograph (METIS) will be equipped with a SCAO system delivering Strehl ratios above 90% at L band (3.5 - 4.1 um) and close to 99% at N band (8 -…

ALF: an asymmetric Lyot wavefront sensor for the ELT/METIS vortex coronagraph

Gilles Orban de Xivry, Olivier Absil, Christian Delacroix +3

Non-common path quasi-static and differential aberrations are one of the big hurdles of direct imaging for current and future high-contrast imaging instruments. They increase speck…

METIS high-contrast imaging: from final design to manufacturing and testing

Olivier Absil, Matthew Kenworthy, Christian Delacroix +21

The Mid-infrared ELT Imager and Spectrograph (METIS) is one of the first-generation scientific instruments for the ELT, built under the supervision of ESO by a consortium of resear…
