GHOST Commissioning Science Results: Identifying a new chemically peculiar star in Reticulum II
Christian R. Hayes, Kim A. Venn, Fletcher Waller +79
The Gemini High-resolution Optical SpecTrograph (GHOST) is the newest high resolution spectrograph to be developed for a large aperture telescope, recently deployed and commissione…
Fast modulation and dithering for the NFIRAOS Pyramid Wavefront Sensor
Edward L. Chapin, David Andersen, Owen Brown +8
The Narrow Field InfraRed Adaptive Optics System (NFIRAOS) for the Thirty Meter Telescope (TMT) will use a natural guide star (NGS) Pyramid Wavefront Sensor (PWFS). A 32-mm diamete…
The infrared imaging spectrograph (IRIS) for TMT: electronics-cable architecture
A. C. Trapp, James Larkin, Ken Magnone +6
The InfraRed Imaging Spectrograph (IRIS) is a first-light instrument for the Thirty Meter Telescope (TMT). It combines a diffraction limited imager and an integral field spectrogra…
Bright Region Reset: an on-detector strategy for minimizing the impacts of atmospheric emission lines on spectral observations
Theodore A. Grosson, Edward L. Chapin, Tim Hardy +4
Observations in the near-infrared using large ground-based telescopes are adversely impacted by bright atmospheric emission lines, particularly the OH Meinel bands. These lines can…
The Science Performance of the Gemini High Resolution Optical Spectrograph
Alan W. McConnachie, Christian R. Hayes, J. Gordon Robertson +46
The Gemini High Resolution Optical Spectrograph (GHOST) is a fiber-fed spectrograph system on the Gemini South telescope that provides simultaneous wavelength coverage from 348 - 1…
InfraRed On-Detector Guide-Windows in the era of Extremely Large Telescopes
Edward L. Chapin, Jennifer Dunn, Tim Hardy +2
Future Extremely Large Telescopes (ELTs) will require advances in Adaptive Optics (AO) systems to fully realize their potential. In addition to separate, dedicated wavefront sensor…
FLAMINGOS-2: The Facility Near-Infrared Wide-field Imager & Multi-Object Spectrograph for Gemini
Stephen Eikenberry, Richard Elston, S. Nicholas Raines +24
We report on the design and status of the FLAMINGOS-2 instrument - a fully-cryogenic facility near-infrared imager and multi-object spectrograph for the Gemini 8-meter telescopes.…
Fast resets of sub-windows on infrared detectors as a strategy for persistence mitigation
Edward L. Chapin, Theodore Grosson, Tim Hardy +1
Persistence effects in HgCdTe infrared detectors cause significant artifacts that can impact the quality of science observations for up to many hours after exposure to bright/satur…
High-Spectral Resolution Dark Holes: Concept, Results, and Promise
William Thompson, Adam B. Johnson, Christian Marois +6
Next generation high contrast imaging instruments face a challenging trade off: they will be required to deliver data with high spectral resolution at a relatively fast cadence (mi…
