Stable fiber-illumination for extremely precise radial velocities with NEID
Shubham Kanodia, Andrea S. J. Lin, Emily Lubar +24
NEID is a high-resolution red-optical precision radial velocity (RV) spectrograph recently commissioned at the WIYN 3.5 m telescope at Kitt Peak National Observatory, Arizona, USA.…
Real-time exposure control and instrument operation with the NEID spectrograph GUI
Arvind F. Gupta, Chad F. Bender, Joe P. Ninan +14
The NEID spectrograph on the WIYN 3.5-m telescope at Kitt Peak has completed its first full year of science operations and is reliably delivering sub-m/s precision radial velocity…
Observing the Sun as a star: Design and early results from the NEID solar feed
Andrea S. J. Lin, Andrew Monson, Suvrath Mahadevan +27
Efforts with extreme-precision radial velocity (EPRV) instruments to detect small-amplitude planets are largely limited, on many timescales, by the effects of stellar variability a…
Ghosts of NEID's Past
Shubham Kanodia, Joe P. Ninan, Andrew J. Monson +14
The NEID spectrograph is a R 120,000 resolution fiber-fed and highly stabilized spectrograph for extreme radial velocity (RV) precision. It is being commissioned at the 3.5…
Solar Contamination in Extreme Precision Radial Velocity Measurements: Deleterious Effects and Prospects for Mitigation
Arpita Roy, Sam Halverson, Suvrath Mahadevan +19
Solar contamination, due to moonlight and atmospheric scattering of sunlight, can cause systematic errors in stellar radial velocity (RV) measurements that significantly detract fr…
Ultra-Stable Environment Control for the NEID Spectrometer: Design and Performance Demonstration
Paul Robertson, Tyler Anderson, Gudmundur Stefansson +30
Two key areas of emphasis in contemporary experimental exoplanet science are the detailed characterization of transiting terrestrial planets, and the search for Earth analog planet…
How Much SETI Has Been Done? Finding Needles in the n-Dimensional Cosmic Haystack
Jason T. Wright, Shubham Kanodia, Emily G. Lubar
Many articulations of the Fermi Paradox have as a premise, implicitly or explicitly, that humanity has searched for signs of extraterrestrial radio transmissions and concluded that…
Overview of the spectrometer optical fiber feed for the Habitable-zone Planet Finder
Shubham Kanodia, Suvrath Mahadevan, Lawrence. W. Ramsey +11
The Habitable-zone Planet Finder (HPF) is a highly stabilized fiber fed precision radial velocity (RV) spectrograph working in the Near Infrared (NIR): 810 - 1280 nm . In this pape…
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…
