An optical cluster finder inevitably suffers from projection effects, where it misidentifies a superposition of galaxies in multiple halos along the line-of-sight as a single cluster. Using mock cluster catalogs built from cosmological N-body simulat

Comparing weak lensing peak counts in baryonic correction models to hydrodynamical simulations

Autor: Max E Lee, Tianhuan Lu, Zoltán Haiman, Jia Liu, Ken Osato

Next-generation weak lensing (WL) surveys, such as by the Vera Rubin Observatory's LSST, the $\textit{Roman}$ Space Telescope, and the $\textit{Euclid}$ space mission, will supply vast amounts of data probing small, highly nonlinear scales. Extractin

Perturbation Theory Remixed: Improved Nonlinearity Modeling beyond Standard Perturbation Theory

Autor: Zhenyuan Wang, Donghui Jeong, Atsushi Taruya, Takahiro Nishimichi, Ken Osato

We present a novel $n$EPT ($n$th-order Eulerian Perturbation Theory) scheme to model the nonlinear density field by the summation up to $n$th-order density fields in perturbation theory. The obtained analytical power spectrum shows excellent agreemen
