First high-contrast results on THD2 testbed after infrastructure upgrade
Iva Laginja, Pierre Baudoz, Rémi Soummer +17
We present the first scientific results delivered by the upgraded THD2 high-contrast imaging testbed. We report two advances enabled by its improved stability and broadband perform…
Enhanced wavefront sensing for the Roman Coronagraph Instrument: Gaussian probes and compact model validation
Lukas Delaye, Iva Laginja, Pierre Baudoz +10
The Coronagraph Instrument on the Roman Space Telescope will be the first space-based system to demonstrate closed-loop focal-plane wavefront sensing and control, a key step toward…
CATKit2-HCI: a collaborative framework for advancing high-contrast coronagraph testbeds
Rémi Soummer, Iva Laginja, Emiel H. Por +19
High-contrast exoplanet imaging requires dedicated laboratory testbeds for the development and validation of coronagraph architectures, wavefront sensing and control methods, calib…
The MICADO first light imager for the ELT: the SCAO module AIT in France, from the beta flat configuration towards the flat and final configurations
Yann Clénet, Vincent Lapeyrère, Eric Gendron +45
MICADO is the designated ELT first light instrument, a near-infrared imager working at the diffraction limit of the telescope thanks to a SCAO and an MCAO mode. Since summer 2024,…
The MICADO first-light imager for the ELT: first steps of the SCAO system MAIT
Yann Clénet, Eric Gendron, Fabrice Vidal +39
MICADO is the ELT first light instrument, an imager working at the diffraction limit of the telescope thanks to two adaptive optics (AO) modes: a single conjugate one (SCAO), avail…
Vector Apodizing Phase Plates for the ELT: From prototype to final optics for METIS and MICADO
J. A. van den Born, R. Landman, D. S. Doelman +12
The first generation of instruments for the upcoming Extremely Large Telescope (ELT) will allow for the direct imaging of exoplanets that were previously below the sensitivity or r…
SUPPPPRESS: Prototyping and testing liquid-crystal vector vortex coronagraphs with reduced polarization leakage
Rico Landman, David Doelman, Jeroen Rietjens +16
The vortex coronagraph is one of the most promising candidates for the Habitable Worlds Observatory (HWO) due to its excellent theoretical performance for an off-axis telescope. A…
The MICADO first light imager for the ELT: Testing the Lyot coronograph prototypes
Pierre Baudoz, Elsa Huby, Olivier Dupuis +3
MICADO, the European Extremely Large Telescope first light imager will feature a dedicated high contrast imaging mode specifically designed for observing and characterizing exoplan…
The MICADO first light imager for the ELT: Sparse Aperture Masks, design and simulations
Elsa Huby, Pierre Baudoz, Sylvestre Lacour +3
MICADO, the European Extremely Large Telescope first light imager will feature a dedicated high contrast imaging mode specifically designed for observing and characterizing exoplan…
The MICADO first light imager for the ELT: MISTHIC simulation pipeline for the high contrast mode of MICADO
Elsa Huby, Pierre Baudoz, Fabrice Vidal +3
We present the Python pipeline that was developed to simulate the high contrast mode images of the MICADO instrument. This mode will comprise three classical Lyot coronagraphs with…
Prototyping liquid-crystal coronagraphs for exo-Earth imaging
Iva Laginja, David Doelman, Frans Snik +12
This paper presents initial results from the ESA-funded ``SUPPPPRESS'' project, which aims to develop high-performance liquid-crystal coronagraphs for direct imaging of Earth-like…
The MICADO first light imager for the ELT: off-axis performance of PSF reconstruction
Matteo Simioni, Daniel Jodlbauer, Carmelo Arcidiacono +14
The highest scientific return, for adaptive optics (AO) observations, is achieved with a reliable reconstruction of the PSF. This is especially true for MICADO@ELT. In this present…
Increasing the raw contrast of VLT/SPHERE with dark hole techniques III. Broadband reference differential imaging of HR\,4796 using a four-quadrant phase mask
Raphael Galicher, Axel Potier, Johan Mazoyer +3
Imaging exoplanetary systems is essential to characterizing exoplanetary systems and to studying planet-disk interactions to understand planet formation. Such imaging in the visibl…
