Brightest Cluster Galaxy ellipticity as proxy for halo shape: Orientation bias, assembly bias, and potential selection effects in SZ-selected clusters
Radhakrishnan Srinivasan, Tae-hyeon Shin, Anja von der Linden +93
The orientation of triaxial galaxy clusters with respect to the line-of-sight is expected to be one of the prime sources of scatter and potential bias in optical observables (e.g.,…
Direct Measurement of Galaxy Assembly Bias using DESI DR1 Data
Zhiwei Shao, Ying Zu, Andrés N. Salcedo +54
We report the first direct measurement of galaxy assembly bias, a critical systematic in cosmology, from the Dark Energy Spectroscopic Instrument (DESI) Bright Galaxy Survey. We in…
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…
Masses of Sunyaev-Zel'dovich Galaxy Clusters Detected by The Atacama Cosmology Telescope: Stacked Lensing Measurements with Subaru HSC Year 3 data
Masato Shirasaki, Cristóbal Sifón, Hironao Miyatake +13
We present a stacked lensing analysis of 96 galaxy clusters selected by the thermal Sunyaev-Zel'dovich (SZ) effect in maps of the cosmic microwave background (CMB). We select foreg…
Impact of Property Covariance on Cluster Weak lensing Scaling Relations
Zhuowen Zhang, Arya Farahi, Daisuke Nagai +5
We present an investigation into a hitherto unexplored systematic that affects the accuracy of galaxy cluster mass estimates with weak gravitational lensing. Specifically, we study…
Optical selection bias and projection effects in stacked galaxy cluster weak lensing
Hao-Yi Wu, Matteo Costanzi, Chun-Hao To +16
Cosmological constraints from current and upcoming galaxy cluster surveys are limited by the accuracy of cluster mass calibration. In particular, optically identified galaxy cluste…
