Forward analytical model for the optical selection bias on galaxy cluster lensing profiles

M. Costanzi, H. Y. Wu, J. H. Esteves +3

Cluster catalogs selected by optical properties are subject to selection biases, primarily arising from unresolved systems along the line of sight. These biases affect key observab…

Weak Lensing Mass Calibration of the ACT DR5 Galaxy Clusters with the DES Year 3 Weak Lensing Data

T. Shin, E. J. Baxter, E. Lee +93

We use weak gravitational lensing measurements from Year 3 Dark Energy Survey data to calibrate the masses of 443 galaxy clusters selected via the Sunyaev-Zel'dovich effect from At…

Dark Energy Survey Year 3 Results: Cosmological Constraints from Cluster Abundances, Weak Lensing, and Galaxy Clustering

DES Collaboration, T. M. C. Abbott, M. Aguena +88

Galaxy clusters provide a unique probe of the late-time cosmic structure and serve as a powerful independent test of the CDM model. This work presents the first set of cosmologi…

Copacabana: A Probabilistic Membership Assignment Method for Galaxy Clusters

J. H. Esteves, M. E. S. Pereira, M. Soares-Santos +52

Cosmological analyses using galaxy clusters in optical/NIR photometric surveys require robust characterization of their galaxy content. Precisely determining which galaxies belong…
