AIROPA II: Modeling Instrumental Aberrations for Off-Axis Point Spread Functions in Adaptive Optics
Anna Ciurlo, Paolo Turri, Gunther Witzel +12
Images obtained with single-conjugate adaptive optics (AO) show spatial variation of the point spread function (PSF) due to both atmospheric anisoplanatism and instrumental aberrat…
Design of SCALES: A 2-5 Micron Coronagraphic Integral Field Spectrograph for Keck Observatory
Andrew Skemer, R. Deno Stelter, Stephanie Sallum +49
We present the design of SCALES (Slicer Combined with Array of Lenslets for Exoplanet Spectroscopy) a new 2-5 micron coronagraphic integral field spectrograph under construction fo…
Using Non-Negative Matrix Factorization to Improve Calibration of the Keck OSIRIS Integral Field Spectrograph
Katelyn Horstman, Michael P. Fitzgerald, James E. Lyke +2
Integral Field Spectrographs (IFS) often require non-trivial calibration techniques to process raw data. The OH Suppressing InfraRed Imaging Spectrograph (OSIRIS) at the W. M. Keck…
Infrared tip-tilt sensing: on-sky experience, lessons learned and unsolved problems
Marcos A. van Dam, Sylvain Oberti, Johann Kolb +3
Infrared tip-tilt sensors (IR TTSs) have been deployed on three different laser guide star adaptive optics (AO) systems on three different telescopes. These IR TTS benefit from the…
Optical and NIR data and modelling of nova V5668 Sgr
L. Takeda, M. Diaz, R. D. Campbell +4
We present HST optical images, Keck-OSIRIS NIR IFS data cubes and Keck-NIRC2 NIR images of nova V5668 Sgr from 2016 to 2019. The observations indicate enhanced emission at the pola…
First light of a holographic aperture mask: Observation at the Keck OSIRIS Imager
David S. Doelman, Joost P. Wardenier, Peter Tuthill +8
We report on the design, construction, and commissioning of a prototype aperture masking technology implemented at the Keck OSIRIS Imager: the holographic aperture mask. Holographi…
