Steward Observatory
CAAO Logo

Founded in 1994, the mission of the Center is to support the advancement of astronomical science by providing the means by which to exploit observations at very high resolutions. The Center demonstrates this focus through its current activities and plans for state-of-the-art adaptive optics systems and related technologies for the many large telescope projects of Steward Observatory, in cooperation with partners from elsewhere on campus, across the country, and around the world. These devices significantly reduce the main limitation of ground-based telescopes, the severe reduction of image quality that results from turbulence in Earth's atmosphere. Operating at near-infrared wavelengths, the Center's AO systems allow imaging and spectroscopy at the limit of resolution of optical diffraction. These advances in astronomers' abilities to view the heavens represent the biggest leap in astronomical technology since the invention of the telescope itself.

Currently, the Center explores and implements a broad range of instrumental and analytical techniques for both ground- and space-based observations. Adaptive Optics systems are not the Center's end products; the enhancement of astronomical science that comes from Adaptive Optics and AO-enabled techniques is an ultimate CAAO goal. This requires of the Center parallel development of both ancillary instrumentation and data reduction capabilities, as well as the invention of new observational techniques, especially space-based techniques for the detection of exo-Earths.

Magellan AO Achieves high Strehl in the visible.


Professor Laird Close and his team have achieved excellent AO images in the visible (55% Strehls at i' --765 nm)) in the test tower in Italy with the MagAO system running in full 800Hz closed loop (400 modes) on R=8 star in 0.8" seeing (V band) and in simulated 33 mph winds. "This is an excellent level of correction, and suggests that MagAO will be a very powerful AO system" says Close. Close thanks his graduates students Jared Males and Derek Kopon and the whole Arcetri and Microgate AO teams for helping achieve these great results in Italy.

Apodized Phase Plate (APP) premieres on VLT


UA astronomers have developed a way to see faint planets previously hidden in their star's glare. The new mode enables scientists to search for planets closer to the star than has been previously possible.
