Cosmological constraints from joint analyses of clusters, galaxies, and weak lensing

The large-scale structure of the universe can be probed by different observables. Galaxy clustering, weak gravitational lensing, galaxy cluster abundances, and cluster clustering are each sensitive to different aspects of cosmic structure formation and are affected by different astrophysical and observational uncertainties. Consistency of different observables presents a strong test of our cosmological model. Further, combinations of all observable lead to the most precise and accurate constraint. In this talk, I will present the cosmological constraints from cluster abundances and auto/cross-correlations of clusters, galaxies, and lensing measured from the Dark Energy Survey. I will discuss the implications of the result and prospects for the Euclid, Rubin, and Roman era.
