The DESI -body Simulation Project I: Testing the Robustness of Simulations for the DESI Dark Time Survey
Cameron Grove, Chia-Hsun Chuang, Ningombam Chandrachani Devi +19
Analysis of large galaxy surveys requires confidence in the robustness of numerical simulation methods. The simulations are used to construct mock galaxy catalogs to validate data…
Numerical investigation of non-Gaussianities in the phase and modulus of density Fourier modes
Jian Qin, Jun Pan, Yu Yu +1
We numerically investigate non-Gaussianities in the late-time cosmological density field in Fourier space. We explore various statistics, including the two-point and three-point pr…
Sensitivity tests of cosmic velocity fields to massive neutrinos
Shuren Zhou, Zhenjie Liu, Qinglin Ma +8
We investigate impacts of massive neutrinos on the cosmic velocity fields, employing high-resolution cosmological -body simulations provided by the information-optimized CUBE co…
Strong Conformity and Assembly Bias: Towards a Physical Understanding of the Galaxy-Halo Connection in SDSS Clusters
Ying Zu, Yunjia Song, Zhiwei Shao +6
Understanding the physical connection between cluster galaxies and massive haloes is key to mitigating systematic uncertainties in next-generation cluster cosmology. We develop a n…
Weak Lensing Magnification Reconstruction with the Modified Internal Linear Combination Method
Shutong Hou, Yu Yu, Pengjie Zhang
Measuring weak lensing cosmic magnification signal is very challenging due to the overwhelming intrinsic clustering in the observed galaxy distribution. In this paper, we modify th…
