A Spectroscopic Road Map for Cosmic Frontier: DESI, DESI-II, Stage-5
David J. Schlegel, Simone Ferraro, Greg Aldering +62
In this white paper, we present an experimental road map for spectroscopic experiments beyond DESI. DESI will be a transformative cosmological survey in the 2020s, mapping 40 milli…
The Commissioning Instrument for the Dark Energy Spectroscopic Instrument
Ashley J. Ross, Paul Martini, Rebecca Coles +8
We describe the design of the Commissioning Instrument for the Dark Energy Spectroscopic Instrument (DESI). DESI will obtain spectra over a 3 degree field of view using the 4-meter…
The Dark Energy Spectroscopic Instrument (DESI)
Michael E. Levi, Lori E. Allen, Anand Raichoor +42
We present the status of the Dark Energy Spectroscopic Instrument (DESI) and its plans and opportunities for the coming decade. DESI construction and its initial five years of oper…
First dark matter search results from the PandaX-I experiment
PandaX Collaboration, Mengjiao Xiao, Xiang Xiao +44
We report on the first dark-matter (DM) search results from PandaX-I, a low threshold dual-phase xenon experiment operating at the China Jinping Underground Laboratory. In the 37-k…
The DESI Instrument Control System: Status and Early Testing
Klaus Honscheid, Ann Elliott, Elizabeth Buckley-Geer +14
The Dark Energy Spectroscopic Instrument (DESI) is a new instrument currently under construction for the Mayall 4-m telescope at Kitt Peak National Observatory. It will consist of…
ProtoDESI: First On-Sky Technology Demonstration for the Dark Energy Spectroscopic Instrument
Parker Fagrelius, Behzad Abareshi, Lori Allen +33
The Dark Energy Spectroscopic Instrument (DESI) is under construction to measure the expansion history of the universe using the baryon acoustic oscillations technique. The spectra…
Investigating reciprocity failure in 1.7-micron cut-off HgCdTe detectors
Michael Schubnell, Tomasz Biesiadzinski, Wolfgang Lorenzon +2
Flux dependent non-linearity (reciprocity failure) in HgCdTe NIR detectors with 1.7 micron cut-off was investigated. A dedicated test station was designed and built to measure reci…
Astro2020 APC White Paper: The MegaMapper: a z > 2 spectroscopic instrument for the study of Inflation and Dark Energy
David J. Schlegel, Juna A. Kollmeier, Greg Aldering +74
MegaMapper is a proposed ground-based experiment to measure Inflation parameters and Dark Energy from galaxy redshifts at 2<z<5. A 6.5-m Magellan telescope will be coupled with DES…
