Constraining Galaxy Cluster Triaxiality via Weak Lensing -- I. Preparation for the Rubin Data Beyond Leading Order

Shenming Fu, Radhakrishnan Srinivasan, Tae-hyeon Shin +13

The 3D mass distributions of galaxy clusters are generally triaxial, a geometry that is difficult to constrain from projected observations. In this work, we measure the projected h…

Optimization of Weak Lensing Lightcone Simulations for Higher-Order Statistics in the LSST era

J. Mena-Fernández, C. Doux, J. Harnois-Déraps +9

We present a framework for generating lightcone simulations tailored to the analysis of Stage-IV cosmic shear data using Higher-Order Statistics (HOS). We revisit key design choice…

Weak lensing mass-richness relation of redMaPPer clusters in the LSST DESC DC2 simulations

Constantin Payerne, Zhuowen Zhang, Michel Aguena +13

Cluster scaling relations are key ingredients in cluster abundance-based cosmological studies. In optical cluster cosmology, where clusters are detected through their richness, clu…
