A Parameter-Masked Mock Data Challenge for Beyond-Two-Point Galaxy Clustering Statistics

2pt Collaboration, Elisabeth Krause, Yosuke Kobayashi +23

The paper presents the first results of the "Beyond-2pt" community data challenge, where participants used various beyond‑two‑point galaxy clustering methods on high‑precision mock…

The Environmental Dependence of Halo Intrinsic Alignments: Stronger Signals in Underdense Regions

Masaya Ichikawa, Jingjing Shi, Toshiki Kurita +3

The paper investigates how the intrinsic alignment of dark matter haloes varies with large‑scale environment, finding that haloes in underdense regions show stronger alignment than…

Large-scale halo velocity correlations and the impact of finite simulation volumes

Yao-Tsung Chuang, Teppei Okumura, Takahiro Nishimichi

The velocity correlation functions directly measured from the peculiar velocity field of dark matter in numerical simulations are known to have an amplitude lower than that predict…

Constraining cosmology with N-body simulations for future spectroscopic galaxy surveys at

Sy-Yun Pu, Teppei Okumura, Chian-Chou Chen +2

Determining the spatial curvature () independent of cosmic microwave background observations plays a key role in revealing the physics of the early universe. The Hubble tensi…

Cosmology and Source Redshift Constraints from Galaxy Clustering and Tomographic Weak Lensing with HSC Y3 and SDSS using the Point-Mass Correction Model

Tianqing Zhang, Xiangchong Li, Sunao Sugiyama +13

The combination of galaxy clustering and weak lensing is a powerful probe of the cosmology model. We present a joint analysis of galaxy clustering and weak lensing cosmology using…

Modelling Galaxy Clustering and Tomographic Galaxy-Galaxy Lensing with HSC Y3 and SDSS using the Point-Mass Correction Model and Redshift Self-Calibration

Tianqing Zhang, Sunao Sugiyama, Surhud More +13

The combination of galaxy-galaxy weak lensing and galaxy clustering is a powerful probe of the cosmological model, and exploration of how to best model and extract this information…
