Description
Optically identified galaxy clusters have the potential to provide some of the most precise cosmological constraints, as they enable the detection of lower-mass clusters. However, they are also highly susceptible to systematic effects, with projection effects being a major challenge. This misidentification of member galaxies introduces anisotropies in the observed distribution of optical clusters, which can bias cosmological analyses. Fortunately, these anisotropies can be constrained through the three-dimensional cluster clustering, which also provides information about velocity fields through redshift-space distortion. In this talk, I will discuss a framework for modeling 3D clustering in optical clusters while accounting for projection effects, highlighting how this approach can mitigate systematics and enhance the robustness of optical cluster cosmology.
