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…

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…
