Laboratory characterization of iLocater
Marcelo Tala Pinto, Marshall C. Johnson, Julia Brady +18
iLocater is a diffraction-limited, fiber-fed spectrograph designed for the Large Binocular Telescope (LBT), which targets high-precision radial velocity measurements in the near-in…
Commissioning and on-sky performance verification of iLocater
Marshall C. Johnson, Marcelo Tala Pinto, Jonathan Crass +59
iLocater is a high-resolution near-infrared extreme precision radial velocity (EPRV) spectrograph that was deployed to the Large Binocular Telescope (LBT) in June 2026. iLocater op…
The Calibration System of the iLocater Spectrograph
Sai Vidyud Senthil Nathan, Jonathan Crass, Julia E. Brady +21
iLocater is a new near-infrared, extreme precision radial velocity (EPRV) instrument delivered to the Large Binocular Telescope in the summer of 2026. The instrument utilizes singl…
Fiber modal noise mitigation by a rotating double scrambler
Gert Raskin, Jacob Pember, Dmytro Rogozin +2
Fiber modal noise is a performance limiting factor in high-resolution spectroscopy, both with respect to achieving high signal-to-noise ratios or when targeting high-precision radi…
Rubidium transitions as wavelength reference for astronomical Doppler spectrographs
Dmytro Rogozin, Tobias Feger, Christian Schwab +10
Precise wavelength calibration is a critical issue for high-resolution spectroscopic observations. The ideal calibration source should be able to provide a very stable and dense gr…
Fiber modal noise mitigation by a rotating double scrambler
Gert Raskin, Dmytro Rogozin, Tom Mladenov +2
Fiber modal noise is a performance limiting factor in high-precision radial velocity measurements with multi-mode fiber-fed high-resolution spectrographs. Traditionally, modal nois…
