Stellar reddening map from DESI imaging and spectroscopy

Rongpu Zhou, Julien Guy, Sergey E. Koposov +54

We present new Galactic dust reddening maps of the high Galactic latitude sky using DESI imaging and spectroscopy. We directly measure the reddening of 2.6 million stars by compari…

Mitigation of DESI fiber assignment incompleteness effect on two-point clustering with small angular scale truncated estimators

M. Pinon, A. de Mattia, P. McDonald +50

We present a method to mitigate the effects of fiber assignment incompleteness in two-point power spectrum and correlation function measurements from galaxy spectroscopic surveys,…

Impact and mitigation of spectroscopic systematics on DESI DR1 clustering measurements

A. Krolewski, J. Yu, A. J. Ross +40

The large scale structure catalogs within DESI Data Release 1 (DR1) use nearly 6 million galaxies and quasars as tracers of the large-scale structure of the universe to measure the…

ELG Spectroscopic Systematics Analysis of the DESI Data Release 1

Jiaxi Yu, Ashley J. Ross, Antoine Rocher +58

Dark Energy Spectroscopic Instrument (DESI) uses more than 2.4 million Emission Line Galaxies (ELGs) for 3D large-scale structure (LSS) analyses in its Data Release 1 (DR1). Such l…

The Construction of Large-scale Structure Catalogs for the Dark Energy Spectroscopic Instrument

A. J. Ross, J. Aguilar, S. Ahlen +83

We present the technical details on how large-scale structure (LSS) catalogs are constructed from redshifts measured from spectra observed by the Dark Energy Spectroscopic Instrume…

Forward modeling fluctuations in the DESI LRGs target sample using image simulations

Hui Kong, Ashley J. Ross, Klaus Honscheid +50

We use the forward modeling pipeline, Obiwan, to study the imaging systematics of the Luminous Red Galaxies (LRGs) targeted by the Dark Energy Spectroscopic Instrument (DESI). We u…

Production of Alternate Realizations of DESI Fiber Assignment for Unbiased Clustering Measurement in Data and Simulations

J. Lasker, A. Carnero Rosell, A. D. Myers +52

A critical requirement of spectroscopic large scale structure analyses is correcting for selection of which galaxies to observe from an isotropic target list. This selection is oft…

The Gravitational Lensing Imprints of DES Y3 Superstructures on the CMB: A Matched Filtering Approach

Umut Demirbozan, Seshadri Nadathur, Ismael Ferrero +63

Low density cosmic voids gravitationally lens the cosmic microwave background (CMB), leaving a negative imprint on the CMB convergence . This effect provides insight into the…
