Unifying cluster and galaxy cosmology analyses using the galaxy-halo connection
Shulei Cao, Hao-Yi Wu, Andrés N. Salcedo +3
Galaxies and galaxy clusters trace the same cosmic density field, but their statistics have been modeled separately in cosmological analyses. We present a unified, simulation-based…

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…
