We present the samples of galaxies and quasars used for DESI 2024 cosmological analyses, drawn from the DESI Data Release 1 (DR1). We describe the construction of large-scale struc…
Extensive analysis of reconstruction algorithms for DESI 2024 baryon acoustic oscillations
X. Chen, Z. Ding, E. Paillas +64
Reconstruction of the baryon acoustic oscillation (BAO) signal has been a standard procedure in BAO analyses over the past decade and has helped to improve the BAO parameter precis…
Mitigating Imaging Systematics for DESI 2024 Emission Line Galaxies and Beyond
A. J. Rosado-Marín, A. J. Ross, H. Seo +56
Emission Line Galaxies (ELGs) are one of the main tracers that the Dark Energy Spectroscopic Instrument (DESI) uses to probe the universe. However, they are afflicted by strong spu…

We present the measurements and cosmological implications of the galaxy two-point clustering using over 4.7 million unique galaxy and quasar redshifts in the range divi…
Fiducial-Cosmology-dependent systematics for the DESI 2024 BAO Analysis
A. Pérez-Fernández, L. Medina-Varela, R. Ruggeri +61
When measuring the Baryon Acoustic Oscillations (BAO) scale from galaxy surveys, one typically assumes a fiducial cosmology when converting redshift measurements into comoving dist…
Unsupervised Searches for Cosmological Parity Violation: Improving Detection Power with the Neural Field Scattering Transform
Matthew Craigie, Peter L. Taylor, Yuan-Sen Ting +3
Recent studies using four-point correlations suggest a parity violation in the galaxy distribution, though the significance of these detections is sensitive to the choice of simula…
Optimal Reconstruction of Baryon Acoustic Oscillations for DESI 2024
