Field-level Neural Network Emulator for Cosmological N-body Simulations

open access: yesThe 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?

open access: yesThe 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.

Large Scale Structure of the Universe [PDF]

open access: yesSymposium - 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 Galaxy–Halo Connection of DESI Luminous Red Galaxies with Subhalo Abundance Matching

open access: yesThe Astrophysical Journal, 2023
We use subhalo abundance and age distribution matching to create magnitude-limited mock galaxy catalogs at z ∼ 0.43, 0.52, and 0.63 with z -band and 3.4 μ m W 1-band absolute magnitudes and r − z and r − W 1 colors. From these magnitude-limited mocks, we

The Galaxy Number Density Profile of Halos

open access: yesThe 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.

Reoriented Memory of Galaxy Spins for the Early Universe

open access: yesThe Astrophysical Journal, 2023
Galaxy spins are believed to retain the initially acquired tendency of being aligned with the intermediate principal axis of the linear tidal field, which disseminates the prospect of using them as a probe of early universe physics. This roseate prospect,

An Observed Transition of Galaxy Spins on Void Surfaces

open access: yesThe Astrophysical Journal Letters, 2023
In linear theory, the galaxy angular momentum vectors that originate from initial tidal interactions with surrounding matter distribution intrinsically develop perpendicular alignments with the directions of maximum matter compression, regardless of ...
