A Semi-Supervised Learning Method for the Identification of Bad Exposures in Large Imaging Surveys
Yufeng Luo, Adam D. Myers, Alex Drlica-Wagner +7
As the data volume of astronomical imaging surveys rapidly increases, traditional methods for image anomaly detection, such as visual inspection by human experts, are becoming impr…
Astrometric Calibration and Performance of the Dark Energy Spectroscopic Instrument Focal Plane
S. Kent, E. Neilsen, K. Honscheid +46
The Dark Energy Spectroscopic Instrument, consisting of 5020 robotic fiber positioners and associated systems on the Mayall telescope at Kitt Peak, Arizona, is carrying out a surve…
Comparing the Photometric Calibration of DESI Imaging and Gaia Synthetic Photometry
Rongpu Zhou, Arjun Dey, Dustin Lang +3
The relative photometric calibration errors in the DESI Legacy Imaging Surveys (LS), which are used for DESI target selection, can leave imprints on the DESI target densities and b…
Performance of the Quasar Spectral Templates for the Dark Energy Spectroscopic Instrument
Allyson Brodzeller, Kyle Dawson, Stephen Bailey +44
Millions of quasar spectra will be collected by the Dark Energy Spectroscopic Instrument (DESI), leading to a four-fold increase in the number of known quasars. High accuracy quasa…
The MegaMapper: A Stage-5 Spectroscopic Instrument Concept for the Study of Inflation and Dark Energy
David J. Schlegel, Juna A. Kollmeier, Greg Aldering +86
In this white paper, we present the MegaMapper concept. The MegaMapper is a proposed ground-based experiment to measure Inflation parameters and Dark Energy from galaxy redshifts a…
The Spectroscopic Data Processing Pipeline for the Dark Energy Spectroscopic Instrument
J. Guy, S. Bailey, A. Kremin +55
We describe the spectroscopic data processing pipeline of the Dark Energy Spectroscopic Instrument (DESI), which is conducting a redshift survey of about 40 million galaxies and qu…
