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…
Long-term performance of the MLR-TT sensor: two-photon polymerization validation in the telescope environment
Robert J. Harris, Philipp Hottinger, Jonathan Crass +2
We report on the long-term optical performance of a two-photon polmerized microlens ring tip-tilt sensor. The study is backed by repeated measurements over the last six years, sinc…
Resolving the Young 2 Cygni Run-away Star into a Binary using iLocater
Justin R. Crepp, Jonathan Crass, Andrew J. Bechter +30
Precision radial velocity (RV) spectrographs that use adaptive optics (AO) show promise to advance telescope observing capabilities beyond those of seeing-limited designs. We are b…
Little iLocater: paving the way for iLocater
Robert J. Harris, Jonathan Crass, Marshall C. Johnson +10
Diffraction-limited radial velocity instruments offer a pathway towards improved precision and stability, and the exploration of new parameter spaces at high spatial and spectral r…
