Self Calibrated Galaxy Groups from the DESI DR1 Bright Galaxy Survey
I. Williams, J. Tinker, K. Wang +45
We present a galaxy group catalog built from Data Release 1 of the Dark Energy Spectroscopic Instrument (DESI) Bright Galaxy Survey, using the Self Calibrated Group Finder. The alg…
Intrinsic Tidal Shear at the Largest Scales: Galaxy Multiplet Alignment in DESI DR2
C. Lamman, J. Aguilar, S. Ahlen +45
We measure the intrinsic alignment (IA) of galaxy multiplets with the large-scale tidal field traced by galaxy positions in DESI Data Release 2. Using the BGS, LRG, and ELG samples…
DESI DR2 Results IV: Alcock-Paczyński Measurements from the Lyman Alpha Forest and Cosmological Constraints
DESI Collaboration, A. G. Adame, J. Aguilar +152
We present Alcock-Paczyński (AP) measurements from the full shape of Lyman- (Ly) forest correlation functions measured from the second data release (DR2) of the Dark Energy S…
DESI DR2 Reference Mocks: Clustering results from UCHUU ELGs and QSOs
R. Vaisakh, J. Lasker, R. Kehoe +44
High-redshift galaxy clustering provides a powerful probe of the growth of structure, testing models of dark matter, dark energy, and galaxy formation during the epoch when the Uni…
Clustering of high-redshift quasars with DESI DR2
M. Charles, P. Martini, A. J. Ross +46
We present clustering measurements for high-redshift quasars using data from the Dark Energy Spectroscopic Instrument Data Release 2. Our sample consists of quasars with $2.0 < z <…
The 3D clustering of Lyman Alpha Emitters measured with DESI
Haruki Ebina, Martin J. White, Rongpu Zhou +44
We present a clustering analysis of Lyman- emitters (LAEs) using spectroscopic observations from the Dark Energy Spectroscopic Instrument (DESI) of candidates selected from the…
Measuring local primordial non-Gaussianity from the clustering of DESI DR1 LRGs and QSOs
Z. Brown, B. Levi, H. Randall +42
We report the first measurement of primordial non-Gaussianity (PNG), parameterized by , in the configuration space two-point correlation function (2pcf). We employ…
DESI Data Release 2 ELGs: Property-dependent subsamples, imaging systematics, and clustering
T. Hagen, K. S. Dawson, Z. Zheng +42
Using emission-line galaxies (ELGs) from the Dark Energy Spectroscopic Instrument (DESI) Data Release 2, we evaluate a property-dependent correction to imaging systematics. We deri…
Local primordial non-Gaussianity using cross-correlations of DESI tracers
A. J. Rosado-Marín, A. J. Ross, H. Seo +46
We constrain local primordial non-Gaussianity by a combined analysis of auto and cross-correlations of DESI DR1 tracers, leveraging LRGs and QSOs as well as ELGs between $0.8<z<3.1…
Large Scale Spectrophotometric Relative Flux Calibration for the Roman High Latitude Wide Area Survey
Alan B. H. Nguyen, Gregory Walth, Ashley J. Ross +4
We consider the application of a ubercalibration-like relative flux calibration to the grism observations of the Roman High Latitude Wide Area Survey (HLWAS). We propose a simplifi…
Cosmological constraints from a joint DESI DR1 Full-Shape and DR2 BAO
D. Forero-Sánchez, H. Gil-Marín, L. Verde +61
We present a cosmological analysis combining full-shape (FS) clustering measurements from the Dark Energy Spectroscopic Instrument (DESI) DR1 with baryon acoustic oscillation (BAO)…
