Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The paper summarizes 70 science cases for the proposed NASA Habitable Worlds Observatory, outlining the observational needs across four scientific pillars and detailing required ca…
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…
On-sky demonstration of second-stage wavefront control with a photonic lantern
Aditya R. Sengupta, Jordan Diaz, Matthew DeMartino +14
Ground-based direct imaging of exoplanets at high contrast requires precise correction of atmospheric turbulence using adaptive optics (AO). The planet-to-star contrast ratio at sm…
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…
An on-sky investigation into factors limiting the performance of Keck-NIRC2 for conducting infrared high-contrast imaging
Rachel Bowens-Rubin, Maïssa Salama, Jayke S. Nguyen +2
The most common instrument used by the exoplanet/brown dwarf direct imaging community at the W.M. Keck Observatory is currently the NIRC2 near-infrared imager. We performed on-sky…
The Santa Cruz Extreme AO Lab (SEAL) 2.0: A reflective, multi-wavelength rebuild
Rebecca Jensen-Clem, Vincent Chambouleyron, Prince Javier +20
The Santa cruz Extreme Adaptive optics Lab (SEAL) is a visible/near-infrared wavelength testbed designed to support technology development for high contrast imaging on large, segme…
