Large Scale Structure of the Universe [PDF]
, 2012 Galaxies are not uniformly distributed in space. On large scales the Universe displays coherent structure, with galaxies residing in groups and clusters on scales of ~1-3 Mpc/h, which lie at the intersections of long filaments of galaxies that are >10 ...

Large Scale Structure of the Universe [PDF]
Symposium - International Astronomical Union, 1997 How is the universe organized on large scales? How did this structure evolve from the unknown initial conditions of a rather smooth early universe to the present time? The answers to these questions will shed light on the cosmology we live in, the amount, composition and distribution of matter in the universe, the initial spectrum of density ...

The Density Parity Model for the Evolution of the Subhalo Inner Spin Alignments with the Cosmic Web
The Astrophysical Journal, 2023 We develop a new model within which the radius-dependent transition of the subhalo inner spins with respect to the cosmic web and the variation of the transition threshold radius ( r _th ) with subhalo mass ( M _vir ), smoothing scale ( r _f ), and ...

Large Scale Structure of the Universe: Current Problems [PDF]
, 1999 The mean power spectrum of galaxies is compared with theoretical models. Possibilities to explain the observed power spectrum are discussed. Superclusters and voids form a quasi-regular lattice of mean cell size 120 Mpc; the main axis of the lattice is ...

The Astrophysical Journal, 2023 We construct accurate emulators for the projected and redshift space galaxy correlation functions and excess surface density as measured by galaxy–galaxy lensing, based on halo occupation distribution modeling.

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.

Radius-dependent Spin Transition of Dark Matter Halos
The Astrophysical Journal, 2023 A numerical detection of the radius-dependent spin transition of dark matter halos is reported. Analyzing the data from the IllustrisTNG simulations, we measure the halo spin vectors at several inner radii within the virial boundaries and investigate ...

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.
