We characterize the earliest galaxy population in the JADES Origins Field, the deepest
imaging field observed with JWST. We make use of ancillary Hubble Space Telescope …

We introduce the AbacusHOD model and present two applications of AbacusHOD and the
AbacusSummit simulations to observations. AbacusHOD is a Halo Occupation Distribution …

Luminous red galaxies (LRGs) and blue star-forming emission-line galaxies (ELGs) are key
tracers of large-scale structure used by cosmological surveys. Theoretical predictions for …

Abstract The One-Percent survey of the Dark Energy Spectroscopic Instrument collected∼
270k emission line galaxies (ELGs) at 0.8< z< 1.6. The high completeness of the sample …

Approximate methods to populate dark-matter haloes with galaxies are of great utility to
galaxy surveys. However, the limitations of simple halo occupation models (HODs) preclude …

We employ the hydrodynamical simulation illustrisTNG to inform the galaxy–halo connection
of the Luminous Red Galaxy (LRG) and Emission Line Galaxy (ELG) samples of the Dark …

In this work, we compare large scale structure observables for stellar mass selected samples
at z= 0, as predicted by two galaxy models, the hydrodynamical simulation IllustrisTNG and …

Modern redshift surveys are tasked with mapping out the galaxy distribution over enormous
distance scales. Existing hydrodynamical simulations, however, do not reach the volumes …

We develop an analytical forward model based on perturbation theory to predict the redshift-
space galaxy overdensity at the field level given a realization of the initial conditions. We find …

Primordial non-Gaussianity of the local type induces a strong scale-dependent bias on the
clustering of halos in the late-time Universe. This signature is particularly promising to …
