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…

Comparison of Models for the Warm-Hot Circumgalactic Medium around Milky Way-like Galaxies
Priyanka Singh, Erwin T. Lau, Yakov Faerman +2
A systematic comparison of the models of the circumgalactic medium (CGM) and their observables is crucial to understanding the predictive power of the models and constraining physi…

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…
