Commissioning and on-sky performance verification of iLocater
Marshall C. Johnson, Marcelo Tala Pinto, Jonathan Crass +59
The paper describes the commissioning and first on‑sky performance of iLocater, a high‑resolution near‑infrared spectrograph on the Large Binocular Telescope, demonstrating its abi…
The Calibration System of the iLocater Spectrograph
Sai Vidyud Senthil Nathan, Jonathan Crass, Julia E. Brady +21
The paper describes the design and implementation of the calibration system for iLocater, a new near‑infrared extreme‑precision radial‑velocity spectrograph on the Large Binocular…
The LBT Project III: LUCI Spectra of Metal-Poor Nebulae
Miqaela K. Weller, Richard W. Pogge, Evan D. Skillman +6
Accurately determining the elemental abundances of a low metallicity nebula strongly depends on measuring the density (n) and temperature (T) of the gas. Because these two…
The LBT Project I: An Improved Determination of the Primordial Helium Abundance -- Project Description, Sample Selection, Observations, and Methodology
Evan D. Skillman, Richard W. Pogge, Erik Aver +9
Extremely low metallicity HII regions have been observed with the goal of determining the primordial helium abundance (). , combined with standard big bang nu…
