On-sky demonstration of a vector Zernike wavefront sensor in a cascaded adaptive optics system
M. Motte, V. Chambouleyron, R. Fétick +13
To directly image and characterise Earth-like exoplanets, future high-contrast instruments will require adaptive-optics systems operating at increasingly high loop frequencies to r…
NIRC2-Pol: First Light of Near-Infrared Polarimetry on Keck II
Briley L. Lewis, Manxuan Zhang, Maxwell A. Millar-Blanchaer +21
NIRC2, the Near Infrared Camera 2 on the Keck II telescope, was recently upgraded with a new suite of polarimetric observing modes. The new polarimetry modes (referred to as NIRC2-…
Enabling Quantitative Polarimetry for Keck/NIRC2: Preliminary Mueller Matrix Model Calibration
Manxuan Zhang, Briley L. Lewis, Maxwell A. Millar-Blanchaer +27
The Keck/NIRC2 infrared imager was upgraded in 2025 with dual-beam polarimetric observing modes spanning approximately 1.1--4.1 microns (JHKL' bands). We present a preliminary JHK…
Ground control to major time-lag: on-sky results of data-driven predictive wavefront control at Keck Observatory
Jules Fowler, Rebeca Jensen-Clem, Sylvain Cetre +12
Directly imaging and characterizing exoplanets requires extreme adaptive optics (XAO), which achieves exquisite wavefront correction over a small (<5") field of view. Temporal erro…
