The Galactic Center with Roman
Sean K. Terry, Matthew W. Hosek, Jessica R. Lu +31
We advocate for a Galactic center (GC) field to be added to the Galactic Bulge Time Domain Survey (GBTDS). The new field would yield high-cadence photometric and astrometric measur…
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…
AIROPA IV: Validating Point Spread Function Reconstruction on Various Science Cases
Sean K. Terry, Jessica R. Lu, Paolo Turri +7
We present an analysis of six independent on-sky datasets taken with the Keck-II/NIRC2 instrument. Using the off-axis point spread function (PSF) reconstruction software AIROPA, we…
AIROPA III: Testing Simulated and On-Sky Data
Paolo Turri, Jessica R. Lu, Gunther Witzel +6
Adaptive optics images from the W. M. Keck Observatory have delivered numerous influential scientific results, including detection of multi-system asteroids, the supermassive black…
Characterizing and Improving the Data Reduction Pipeline for the Keck OSIRIS Integral Field Spectrograph
Kelly E. Lockhart, Tuan Do, James E. Larkin +15
OSIRIS is a near-infrared (1.0--2.4 m) integral field spectrograph operating behind the adaptive optics system at Keck Observatory, and is one of the first lenslet-based integra…
