Gravitas: A Browser-Based Astrophysics Laboratory for Prediction, Measurement, and Discovery
Carl Ziegler
Astronomy students are often asked to reason about systems that cannot be handled in a laboratory, evolve over inaccessible timescales, or reveal themselves only through indirect m…
Robo-AO-2: entering the era of automated science operations, hybrid wavefront sensing, and adaptive secondary integration
Christoph Baranec, Reed Riddle, James Ou +10
We present the first science results and new technical milestones from the Robo-AO-2 facility at the University of Hawaii 2.2-m telescope. Following successful commissioning, the s…
Laser-only adaptive optics achieves significant image quality gains compared to seeing-limited observations over the entire sky
Ward S. Howard, Nicholas M. Law, Carl A. Ziegler +2
Adaptive optics laser guide star systems perform atmospheric correction of stellar wavefronts in two parts: stellar tip-tilt and high-spatial-order laser-correction. The requiremen…
SRAO: optical design and the dual-knife-edge WFS
Carl Ziegler, Nicholas M. Law, Andrei Tokovinin
The Southern Robotic Adaptive Optics (SRAO) instrument will bring the proven high-efficiency capabilities of Robo-AO to the Southern-Hemisphere, providing the unique capability to…
