Towards Autodifferentiable Point Spread Function Modelling for the VLT/ERIS Vortex Coronagraph
P. Van de Walle Suarez, G. Orban De Xivry, O. Absil +3
High-contrast imaging of exoplanets is limited by the presence of quasi-static speckles and existing post-processing methods remain above the theoretical noise limit. We investigat…
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 -…
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…
Molecular Outflows in the Nucleus of the Nearby Compton-thick AGN NGC 3079
Ming-Yi Lin, Anne Medling, Richard Davies +14
We present Northern Extended Millimeter Array (NOEMA) observations of the CO (2-1) molecular gas kinematics in the nearby Compton-thick Seyfert 2 galaxy NGC 3079, with an angular r…
Focal plane wavefront control with model-based reinforcement learning
Jalo Nousiainen, Iremsu Taskin, Markus Kasper +2
The direct imaging of potentially habitable exoplanets is one prime science case for high-contrast imaging instruments on extremely large telescopes. Most such exoplanets orbit clo…
MIRAC-5 on the MMT with MAPS: annular groove phase mask N-band coronagraphic upgrade
Alyssa L. Miller, Jarron Leisenring, Michael Meyer +15
We describe the coronagraphic upgrade underway for the Mid-Infrared Array Camera-5 (MIRAC-5) to be used with the 6.5-m MMT telescope utilizing the new MMT Adaptive optics exoPlanet…
