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 Large-Scale Structure of the Universe [PDF]
, 2013 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 Mpc/h in length.

The large-scale structure of the universe
Uspekhi Fizicheskih Nauk, 1983 A survey is given of theories for the origin of large-scale structure in the universe: clusters and superclusters of galaxies, and vast black regions practically devoid of galaxies. Special attention is paid to the theory of a neutrino-dominated universe—a cosmology in which electron neutrinos with a rest mass of a few tens of electron volts would ...

Signatures of Primordial Gravitational Waves on the Large-Scale Structure of the Universe. [PDF]
Physical Review Letters, 2021 We study the generation and evolution of second-order energy-density perturbations arising from primordial gravitational waves. Such "tensor-induced scalar modes" approximately evolve as standard linear matter perturbations and may leave observable ...

Field-level Neural Network Emulator for Cosmological N-body Simulations
The Astrophysical Journal, 2023 We build a field-level emulator for cosmic structure formation that is accurate in the nonlinear regime. Our emulator consists of two convolutional neural networks trained to output the nonlinear displacements and velocities of N -body simulation ...

Ho’oleilana: An Individual Baryon Acoustic Oscillation?
The Astrophysical Journal, 2023 Theory of the physics of the early hot universe leads to a prediction of baryon acoustic oscillations (BAOs) that has received confirmation from the pairwise separations of galaxies in samples of hundreds of thousands of objects.

The Astrophysical Journal, 2023 We present two new diagnostics based on the intrinsic shape alignments of group/cluster size dark matter halos to disentangle the effect of f ( R ) gravity from that of massive neutrinos.
