Spatial frequency response and sensitivity of the nonlinear curvature wavefront sensor
Stanimir Letchev, Jonathan Crass, Justin R. Crepp +1
The nonlinear curvature wavefront sensor (nlCWFS) has been shown to be a promising alternative to existing wavefront sensor designs. Theoretical studies indicate that the inherent…
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…
The final design of the iLocater spectrograph: An optimized architecture for diffraction-limited EPRV instruments
Jonathan Crass, David Aikens, Joaquin Mason +7
iLocater is a near-infrared, extremely precise radial velocity (EPRV) spectrograph under construction for the dual 8.4 m diameter Large Binocular Telescope (LBT). The instrument wi…
Characterizing and Mitigating the Impact of Telluric Absorption in Precise Radial Velocities
Sharon Xuesong Wang, Natasha Latouf, Peter Plavchan +7
Precise radial velocity (PRV) surveys are important for the search of Earth analogs around nearby bright stars. Such planets induce a small stellar reflex motion with RV amplitude…
