Robustness of pairwise kinematic Sunyaev-Zel'dovich effect to optical-cluster-selection bias
Y. -H. Hsu, D. Gruen, P. A. Gallardo +5
The pairwise kinematic Sunyaev-Zel'dovich(kSZ) effect measures both the pairwise motion between galaxy groups and clusters and the amount of gas within them, providing a tracer for…
Dark Energy Survey Year 6 Results: Cosmological Constraints from Galaxy Clustering and Weak Lensing
DES Collaboration, T. M. C. Abbott, M. Adamow +169
We present cosmology results combining galaxy clustering and weak gravitational lensing measured in the full six years (Y6) of observations by the Dark Energy Survey (DES) covering…
What Galaxy Clusters Have to Say About Dynamical Dark Energy and
Andrés N. Salcedo, Eduardo Rozo, Hao-Yi Wu +4
We show that, in flat CDM, low-redshift structure probes -- cluster abundances, 32-point analyses, and full-shape clustering -- are mutually consistent, jointly deliver…
Cosmological Constraints from Dark Energy Survey Year 1 Cluster Lensing and Abundances with Simulation-based Forward-Modeling
Andrés N. Salcedo, Eduardo Rozo, Hao-Yi Wu +7
We present a simulation-based forward-modeling framework for cosmological inference from optical galaxy-cluster samples, and apply it to the abundance and weak-lensing signals of D…
Association between optically identified galaxy clusters and the underlying dark matter halos
DES Collaboration, Shulei Cao, Hao-Yi Wu +10
Clusters of galaxies trace massive dark matter halos in the Universe, but they can include multiple halos projected along lines of sight. As a case study, we quantify the propertie…
Dark Energy Survey Year 3 Results: Cosmological Constraints from Cluster Abundances, Weak Lensing, and Galaxy Clustering
DES Collaboration, T. M. C. Abbott, M. Aguena +88
Galaxy clusters provide a unique probe of the late-time cosmic structure and serve as a powerful independent test of the CDM model. This work presents the first set of cosmolog…
