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…
Spectral interferometric wavefront sensing: a solution for petalometry at Subaru/SCExAO
Vincent Deo, Sebastien Vievard, Manon Lallement +12
The petaling effect, induced by pupil fragmentation from the telescope spider, drastically affects the performance of high contrast instruments by inducing core splitting on the PS…
Photonic chip for visible interferometry: laboratory characterization and comparison with the theoretical model
Manon Lallement, Sylvestre Lacour, Elsa Huby +15

Spectroscopy using a visible photonic lantern at the Subaru telescope: Laboratory characterization and first on-sky demonstration on Ikiiki (α Leo) and `Aua (α Ori)
Sébastien Vievard, Manon Lallement, Sergio Leon-Saval +23
Photonic lanterns are waveguide devices enabling high throughput single mode spectroscopy and high angular resolution. We aim to present the first on-sky demonstration of a photoni…
The MICADO first light imager for the ELT: Sparse Aperture Masks, design and simulations
Elsa Huby, Pierre Baudoz, Sylvestre Lacour +3

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…
Efficiently Searching for Close-in Companions around Young M Dwarfs using a Multi-year PSF Library
Aniket Sanghi, Jerry Xuan, Jason Wang +7
We present Super-RDI, a unique framework for the application of reference star differential imaging (RDI) to Keck/NIRC2 high-contrast imaging observations with the vortex coronagra…
A Survey of Protoplanetary Disks Using the Keck/NIRC2 Vortex Coronagraph
Nicole L. Wallack, Jean-Baptiste Ruffio, Garreth Ruane +34
Recent Atacama Large Millimeter/submillimeter Array (ALMA) observations of protoplanetary disks in the millimeter continuum have shown a variety of radial gaps, cavities, and spira…
Visible Photonic Lantern integration, characterization and on-sky testing on Subaru/SCExAO
Sébastien Vievard, Manon Lallement, Sergio Leon-Saval +23
A Photonic Lantern (PL) is a novel device that efficiently converts a multi-mode fiber into several single-mode fibers. When coupled with an extreme adaptive optics (ExAO) system a…
The VLT/ERIS vortex coronagraph: design, pointing control, and on-sky performance
Gilles Orban de Xivry, Olivier Absil, Robert J. De Rosa +14
The Enhanced Resolution Imager and Spectrograph (ERIS) is the new near-infrared instrument at the VLT-UT4. ERIS replaces and extends the observational capabilities formerly provide…
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…
