The Galaxy Number Density Profile of Halos
The Astrophysical Journal, 2023 More precise measurements of galaxy clustering will be provided by the next generation of galaxy surveys, such as DESI, WALLABY, and the Square Kilometre Array.

Plasma Suppression of Large Scale Structure Formation in the Universe [PDF]
, 2007 We point out that during the reionization epoch of the cosmic history, the plasma collective effect among the ordinary matter would suppress the large scale structure formation.

Classifying the large-scale structure of the universe with deep neural networks [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We present the first application of deep neural networks to the semantic segmentation of cosmological filaments and walls in the Large Scale Structure of the Universe.

Spurious Correlations between Galaxies and Multiepoch Image Stacks in the DESI Legacy Surveys
The Astrophysical Journal Supplement Series, 2023 A nonnegligible source of systematic bias in cosmological analyses of galaxy surveys is the on-sky modulation that is caused by foregrounds and variable image characteristics, such as observing conditions.

Stellar-reddening-based Extinction Maps for Cosmological Applications
The Astrophysical Journal, 2023 Cosmological surveys must correct their observations for the reddening of extragalactic objects by Galactic dust. Existing dust maps, however, have been found to have spatial correlations with the large-scale structure of the Universe.

Cosmological Shock Waves and Their Role in the Large-Scale Structure of the Universe [PDF]
, 2003 We study the properties of cosmological shock waves identified in high-resolution, N-body/hydrodynamic simulations of a ΛCDM universe and their role on thermalization of gas and acceleration of nonthermal, cosmic-ray (CR) particles.
