Forecasting cosmological constraints from the nonlinear halo density field with Zel'dovich-inspired transform

Yu Zhou, Yun Wang, Haozhe Zhang +4

The Zel'dovich-inspired (ZI) transform is a local nonlinear transform of the density field that can Gaussianize the late-time matter field and recover information from higher-order…

ELUCID-DESI II. Revealing dark matter mass, tidal, and velocity (MTV) fields using galaxy group phase information

Qingyang Li, Xiaohu Yang, Wensheng Hong +24

We introduce a novel method for reconstructing the cosmic mass, tidal, and velocity (MTV) fields over the redshift range using the phase information of galaxy groups.…

The Effect of Slitless Spectroscopic Redshift Uncertainty and Interlopers on BAO Measurements from CSST-like Samples

Zhejie Ding, Yu Yu, Pengjie Zhang

The baryon acoustic oscillations (BAO) is a vital probe to measure cosmological distances and constrain dark energy. The ongoing and near-future space-based telescopes, including t…

Enhancing Morphological Measurements of Cosmic Web with Delaunay Tessellation Field Estimation

Yu Liu, Yu Yu, Pengjie Zhang +1

The density fields constructed by traditional mass assignment methods are susceptible to irritating discreteness, which hinders morphological measurements of cosmic large-scale str…

Weak Lensing Reconstruction by Counting DECaLS Galaxies

Jian Qin, Pengjie Zhang, Haojie Xu +4

Alternative to weak lensing measurements through cosmic shear, we present a weak lensing convergence map reconstructed through cosmic magnification effect in DECaLS galaxie…
