Relativistic redshift of the star S0-2 orbiting the Galactic center supermassive black hole
Tuan Do, Aurelien Hees, Andrea Ghez +26
General Relativity predicts that a star passing close to a supermassive black hole should exhibit a relativistic redshift. We test this using observations of the Galactic center st…
Io's Volcanic Activity from Time Domain Adaptive Optics Observations: 2013-2018
Katherine de Kleer, Imke de Pater, Edward M. Molter +11
We present measurements of the near-infrared brightness of Io's hot spots derived from 2-5 micron imaging with adaptive optics on the Keck and Gemini N telescopes. The data were ob…
An adaptive scheduling tool to optimize measurements to reach a scientific objective: methodology and application to the measurements of stellar orbits in the Galactic Center
A. Hees, A. Dehghanfar, T. Do +4
In various fields of physics and astronomy, access to experimental facilities or to telescopes is becoming more and more competitive and limited. It becomes therefore important to…
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…
Analysis of Neptune's 2017 Bright Equatorial Storm
Edward Molter, Imke de Pater, Statia Luszcz-Cook +22
We report the discovery of a large (8500 km diameter) infrared-bright storm at Neptune's equator in June 2017. We tracked the storm over a period of 7 months with high-cadenc…
3D photoionization models of nova V723 Cas
L. Takeda, M. Diaz, R. Campbell +1
We present modeling and analysis of the ejecta of nova V723 Cas based on spatially resolved IR spectroscopic data from Keck-OSIRIS, with LGSAO (adaptive optics module). The 3D phot…
