Keck all sky precision adaptive optics: project overview

Abstract: We present the status and plans for the Keck All sky Precision Adaptive optics (KAPA) program. KAPA includes four key science programs, an upgrade to the Keck I laser guide star (LGS) adaptive optics (AO) facility to improve image quality and sky coverage, AO telemetry based point spread function (PSF) estimates for all science exposures, and an educational component focused on broadening the participation of women and underrepresented groups in instrumentation. For the purpose of this conference we will focus… Show more

“…Recent experience with the Dark Energy Survey [62,63] shows that multiply imaged quasars can be discovered in large numbers using ground based imaging data, and confirmed using existing and planned spectroscopic and adaptive optics capabilities [64]. The United Sates Extremely Large Telescope Program will be essential to provide deep adaptive-optics assisted spectroscopy to measure spatially resolved stellar kinematics of the deflectors and break the mass sheet degeneracy [59].…”

“…The Keck-I and Keck-II AO systems have been used to deliver very-high-resolution imaging for well over two decades and have been continuously upgraded and fitted with newer-generation hardware. The future of both Keck telescopes is filled with several promising next-generation updates 1,2 As a result of imperfect knowledge of the spatially varying (i.e., off-axis) PSF in these AO systems, very precise astrometry and photometry for a large majority of stellar sources in crowded fields (for example) has been limited. The Anisoplanatic and Instrumental Reconstruction of Off-axis PSFs for AO (AIROPA) is a suite of software packages that utilize phase-diversity measurements, atmospheric profile data, and wave propagation through both turbulence and optical systems.…”
