Simulation Tests of PSF Modeling for Cosmic Shear with the Vera C. Rubin Observatory
Claire-Alice Hébert, Erin S. Sheldon, Tianqing Zhang +3
Exceptional control of systematic effects is required in order to achieve unbiased cosmic shear two-point correlation function measurements with the next generation of galaxy imagi…
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.,…
Reanalysis of Stage-III cosmic shear surveys: A comprehensive study of shear diagnostic tests
Jazmine Jefferson, Yuuki Omori, Chihway Chang +12
In recent years, shear catalogs have been released by various Stage-III weak lensing surveys including the Kilo-Degree Survey, the Dark Energy Survey, and the Hyper Suprime-Cam Sub…
Mitigating Shear-dependent Object Detection Biases with Metacalibration
Erin S. Sheldon, Matthew R. Becker, Niall MacCrann +1
Metacalibration is a new technique for measuring weak gravitational lensing shear that is unbiased for isolated galaxy images. In this work we test metacalibration with overlapping…
Detection of cross-correlation between gravitational lensing and gamma rays
S. Ammazzalorso, D. Gruen, M. Regis +75
In recent years, many gamma-ray sources have been identified, yet the unresolved component hosts valuable information on the faintest emission. In order to extract it, a cross-corr…
