DESI DR1 Ly forest: 3D full-shape analysis and cosmological constraints
Andrei Cuceu, Hiram K. Herrera-Alcantar, Calum Gordon +75
We perform an analysis of the full shapes of Lyman- (Ly) forest correlation functions measured from the first data release (DR1) of the Dark Energy Spectroscopic Instrument (…
Prototyping of 6.2-mm-Pitch Fiber Positioner Modules for Stage-V Telescope Instrumentation
Malak Galal, Maxime Rombach, Jonathan Wei +18
Small-pitch populated focal planes are essential enabling technologies for the next generation of highly multiplexed astronomical instruments. As modern astrophysics relies on mass…
DESI DR1 Ly 1D power spectrum: The optimal estimator measurement
N. G. Karaçaylı, P. Martini, J. Aguilar +61
The one-dimensional power spectrum of Ly forest offers rich insights into cosmological and astrophysical parameters, including constraints on the sum of neutri…
Using Active Learning to Improve Quasar Identification for the DESI Spectra Processing Pipeline
Dylan Green, David Kirkby, J. Aguilar +51
The Dark Energy Spectroscopic Instrument (DESI) survey uses an automatic spectral classification pipeline to classify spectra. QuasarNET is a convolutional neural network used as p…
Optimizing Charge-coupled Device Readout Enabled by the Floating-Gate Amplifier
Kenneth W. Lin, Abby Bault, Armin Karcher +4
Multiple-Amplifier Sensing (MAS) charge-coupled devices (CCDs) have recently been shown to be promising silicon detectors that meet noise sensitivity requirements for next generati…
Data Release 1 of the Dark Energy Spectroscopic Instrument
DESI Collaboration, M. Abdul Karim, A. G. Adame +306
In 2021 May the Dark Energy Spectroscopic Instrument (DESI) collaboration began a 5-year spectroscopic redshift survey to produce a detailed map of the evolving three-dimensional s…
Construction of the Damped Ly Absorber Catalog for DESI DR2 Ly BAO
A. Brodzeller, M. Wolfson, D. M. Santos +96
We present the Damped Ly Toolkit for automated detection and characterization of Damped Ly absorbers (DLA) in quasar spectra. Our method uses quasar spectral templates with a…
DESI DR2 Results I: Baryon Acoustic Oscillations from the Lyman Alpha Forest
DESI Collaboration, M. Abdul-Karim, J. Aguilar +147
We present the Baryon Acoustic Oscillation (BAO) measurements with the Lyman-alpha (LyA) forest from the second data release (DR2) of the Dark Energy Spectroscopic Instrument (DESI…
DESI DR2 Results II: Measurements of Baryon Acoustic Oscillations and Cosmological Constraints
DESI Collaboration, M. Abdul-Karim, J. Aguilar +184
We present baryon acoustic oscillation (BAO) measurements from more than 14 million galaxies and quasars drawn from the Dark Energy Spectroscopic Instrument (DESI) Data Release 2 (…
The Spectroscopic Stage-5 Experiment
Robert Besuner, Arjun Dey, Alex Drlica-Wagner +106
The existence, properties, and dynamics of the dark sectors of our universe pose fundamental challenges to our current model of physics, and large-scale astronomical surveys may be…
