Temporal Variations of Telluric Water Vapor Absorption at Apache Point Observatory
Dan Li, Cullen H. Blake, David Nidever +1
Time-variable absorption by water vapor in Earth's atmosphere presents an important source of systematic error for a wide range of ground-based astronomical measurements, particula…
A Low-cost Environmental Control System for Precise Radial Velocity Spectrometers
David H. Sliski, Cullen H. Blake, Samuel Halverson
We present an Environmental Control System (ECS) designed to achieve milliKelvin (mK) level temperature stability for small-scale astronomical instruments. This ECS is inexpensive…
Towards Space-like Photometric Precision from the Ground with Beam-Shaping Diffusers
Gudmundur Stefansson, Suvrath Mahadevan, Leslie Hebb +21
We demonstrate a path to hitherto unachievable differential photometric precisions from the ground, both in the optical and near-infrared (NIR), using custom-fabricated beam-shapin…
An efficient, compact, and versatile fiber double scrambler for high precision radial velocity instruments
Samuel Halverson, Arpita Roy, Suvrath Mahadevan +5
We present the design and test results of a compact optical fiber double-scrambler for high-resolution Doppler radial velocity instruments. This device consists of a single optic:…
Development of a New, Precise Near-infrared Doppler Wavelength Reference: A Fiber Fabry-Perot Interferometer
Samuel Halverson, Suvrath Mahadevan, Lawrence Ramsey +5
We present the ongoing development of a commercially available Micron Optics fiber-Fabry Perot Interferometer as a precise, stable, easy to use, and economic spectrograph reference…
