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…

Keck Observatory as an HWO Testbed: validating wavefront sensing and control schemes on a large segmented aperture in parallel with high-contrast science
Maïssa Salama, Rebecca Jensen-Clem, Mahawa Cissé +6
Exoplanet direct imaging allows us to directly probe and characterize an exoplanet's atmosphere, searching for signs of life in its atmospheric signatures. Directly imaging an Eart…
