StarDICE I: sensor calibration bench and absolute photometric calibration of a Sony IMX411 sensor
Marc Betoule, Sarah Antier, Emmanuel Bertin +18
The Hubble diagram of type-Ia supernovae (SNe-Ia) provides cosmological constraints on the nature of dark energy with an accuracy limited by the flux calibration of currently avail…
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…
Target Selection and Validation of DESI Emission Line Galaxies
A. Raichoor, J. Moustakas, Jeffrey A. Newman +48
The Dark Energy Spectroscopic Instrument (DESI) will precisely constrain cosmic expansion and the growth of structure by collecting 40 million extra-galactic redshifts across…
Target Selection and Validation of DESI Quasars
Edmond Chaussidon, Christophe Yèche, Nathalie Palanque-Delabrouille +54
The Dark Energy Spectroscopic Instrument (DESI) survey will measure large-scale structures using quasars as direct tracers of dark matter in the redshift range 0.9<z<2.1 and using…
DESI Bright Galaxy Survey: Final Target Selection, Design, and Validation
ChangHoon Hahn, Michael J. Wilson, Omar Ruiz-Macias +57
Over the next five years, the Dark Energy Spectroscopic Instrument (DESI) will use 10 spectrographs with 5000 fibers on the 4m Mayall Telescope at Kitt Peak National Observatory to…
Measurement of telescope transmission using a Collimated Beam Projector
Thierry Souverin, Jérémy Neveu, Marc Betoule +17
The number of type Ia supernova observations will see a significant growth within the next decade, especially thanks to the Legacy Survey of Space and Time undertaken by the Vera R…
