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 deliveri…

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…

Direct Measurement of Galaxy Assembly Bias using DESI DR1 Data

Zhiwei Shao, Ying Zu, Andrés N. Salcedo +54

We report the first direct measurement of galaxy assembly bias, a critical systematic in cosmology, from the Dark Energy Spectroscopic Instrument (DESI) Bright Galaxy Survey. We in…

DESI DR2 reference mocks: clustering results from Uchuu-BGS and LRG

E. Fernández-García, F. Prada, A. Smith +64

The aim of this work is to construct mock galaxy catalogues that accurately reproduce the redshift evolution of galaxy number density, clustering statistics, and baryonic propertie…

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…

Multiprobe cosmology forecasts from halo-occupation-distribution-based forward modeling of galaxy and void statistics

Andrés N. Salcedo, Alice Pisani, Nico Hamaus

The large under-dense regions in the cosmological matter density field, known as cosmic voids, are powerful probes of cosmology but their potential is currently under-exploited. Ob…
