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 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…
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…
