Dark Energy Survey Year 6 Results: Redshift Calibration of the MagLim++ Lens Sample

G. Giannini, A. Alarcon, W d'Assignies, G. M. Bernstein et autres

In this work, we derive and calibrate the redshift distribution of the MagLim++ lens galaxy sample used in the Dark Energy Survey Year 6 (DES Y6) 3x2pt cosmology analysis. The 3x2pt analysis combines galaxy clustering from the lens galaxy sample and weak …

Dark Energy Survey Year 3 results: Cosmological constraints from galaxy clustering and galaxy-galaxy lensing using the MagLim lens sample

A. Porredon, M. Crocce, J. Elvin-Poole, R. Cawthon et autres

The cosmological information extracted from photometric surveys is most robust when multiple probes of the large scale structure of the Universe are used. Two of the most sensitive probes are the clustering of galaxies and the tangential shear of background galaxy shapes …

Cosmic shear in harmonic space from the Dark Energy Survey Year 1 Data: compatibility with configuration space results

H. Camacho, F. Andrade-Oliveira, A. Troja, R. Rosenfeld et autres

ABSTRACT We perform a cosmic shear analysis in harmonic space using the first year of data collected by the Dark Energy Survey (DES-Y1). We measure the cosmic weak lensing shear power spectra using the metacalibration catalogue and perform a likelihood analysis within …

Dark Energy Survey Year 3 results: Cosmology from combined galaxy clustering and lensing validation on cosmological simulations

Joseph DeRose, Risa H. Wechsler, M. R. Becker, E. S. Rykoff et autres

We present a validation of the Dark Energy Survey Year 3 (DES Y3) $3\ifmmode\times\else\texttimes\fi{}2$-point analysis choices by testing them on Buzzard2.0, a new suite of cosmological simulations that is tailored for the testing and validation of combined galaxy clustering and weak-lensing analyses. …

Dark Energy Survey Year 3 results: Exploiting small-scale information with lensing shear ratios

C. Sánchez, J. Prat, Georgios Zacharegkas, Shivam Pandey et autres

Using the first three years of data from the Dark Energy Survey (DES), we use ratios of small-scale galaxy-galaxy lensing measurements around the same lens sample to constrain source redshift uncertainties, intrinsic alignments and other systematics or nuisance parameters of our model. …

Dark energy survey year 3 results: High-precision measurement and modeling of galaxy-galaxy lensing

J. Prat, J. Blazek, C. Sánchez, I. Tutusaus et autres

We present and characterize the galaxy-galaxy lensing signal measured using the first three years of data from the Dark Energy Survey (DES Y3) covering $4132\text{ }\text{ }{\mathrm{deg}}^{2}$. These galaxy-galaxy measurements are used in the DES Y3 $3\ifmmode\times\else\texttimes\fi{}2\text{ }\text{ }\mathrm{pt}$ cosmological analysis, which …

The Observed Evolution of the Stellar Mass–Halo Mass Relation for Brightest Central Galaxies

Jesse B. Golden-Marx, C. J. Miller, Y. Zhang, R. L. C. Ogando et autres

Abstract We quantify evolution in the cluster-scale stellar mass–halo mass (SMHM) relation’s parameters using 2323 clusters and brightest central galaxies (BCGs) over the redshift range 0.03 ≤ z ≤ 0.60. The precision on the inferred SMHM parameters is improved by including the …

E. Krause, Joseph DeRose, N. MacCrann, Bhuvnesh Jain et autres

We constrain cosmological parameters and galaxy-bias parameters using the combination of galaxy clustering and galaxy-galaxy lensing measurements from the Dark Energy Survey (DES) year-3 data. We describe our modeling framework and choice of scales analyzed, validating their robustness to theoretical uncertainties in …
