Aug 1, 2023 · The 1D marginalized probability distributions of dark energy EoS parameter(s), constrained from the lens-redshift distribution test for ω CDM model (left panel) and ω 0 ω a CDM model (middle and right panels), respectively.
We perform high-resolution ray-tracing simulations to investigate probability distribution functions (PDFs) of lensing convergence, shear, and magnification on distant sources up to the redshift of z s = 20. We pay particular attention to the shot noise effect in N-body simulations by explicitly showing how it affects the variance of the ...
