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 iLocater cryostat and thermal control system: enabling extremely precise radial velocity measurements for diffraction-limited spectrographs
Jonathan Crass, Nandini Sadagopan, Matthew Misch +10
Extremely precise radial velocity (EPRV) measurements are critical for characterizing nearby terrestrial worlds. EPRV instrument precisions of $σ_{\mathrm{RV}} = 1-10\,\mathrm{cm/s…
Origins Space Telescope Mission Concept Study Report
M. Meixner, A. Cooray, D. Leisawitz +66
The Origins Space Telescope (Origins) traces our cosmic history, from the formation of the first galaxies and the rise of metals to the development of habitable worlds and present-…
iLocater: A Diffraction-limited Doppler Spectrometer for the Large Binocular Telescope
Justin R. Crepp, Jonathan Crass, David King +31
We are developing a stable and precise spectrograph for the Large Binocular Telescope (LBT) named "iLocater." The instrument comprises three principal components: a cross-dispersed…
The iLocater cryostat: design and thermal control strategy for precision radial velocity measurements
Jonathan Crass, Louis G. Fantano, Frederick R. Hearty +8
The current generation of precision radial velocity (RV) spectrographs are seeing-limited instruments. In order to achieve high spectral resolution on 8m class telescopes, these sp…
