Impact of crosshatch patterns in H2RGs on high precision radial velocity measurements: Exploration of measurement and mitigation paths with HPF
Joe P. Ninan, Suvrath Mahadevan, Gudmundur Stefansson +9
Teledyne's H2RG detector images suffer from cross-hatch like patterns which arises from sub-pixel quantum efficiency (QE) variation. In this paper we present our measurements of th…
Ultra-Stable Environment Control for the NEID Spectrometer: Design and Performance Demonstration
Paul Robertson, Tyler Anderson, Gudmundur Stefansson +30
Two key areas of emphasis in contemporary experimental exoplanet science are the detailed characterization of transiting terrestrial planets, and the search for Earth analog planet…
A 30 GHz electro-optic frequency comb spanning 300 THz in the near infrared and visible
Andrew J. Metcalf, Connor D. Fredrick, Ryan C. Terrien +2
Beginning with a continuous wave laser at 1064 nm, we generate a 30 GHz electro-optic frequency comb which contains 100 lines spanning 3 THz. The initial comb is subsequently ampli…
A Versatile Technique to Enable sub-milli-Kelvin Instrument Stability for Precise Radial Velocity Measurements: Tests with the Habitable-zone Planet Finder
Gudmundur Stefansson, Frederick Hearty, Paul Robertson +13
Insufficient instrument thermo-mechanical stability is one of the many roadblocks for achieving 10cm/s Doppler radial velocity (RV) precision, the precision needed to detect Earth-…
