Abstract The standard Λ Cold Dark Matter (ΛCDM) cosmological model provides a good
description of a wide range of astrophysical and cosmological data. However, there are a …

We review one of the most fruitful areas in cosmology today that bridge theory and data—the
temporal growth of large-scale structure. We go over the growth's physical foundations, and …

The cosmological principle (CP)—the notion that the Universe is spatially isotropic and
homogeneous on large scales—underlies a century of progress in cosmology. It is …

We present an estimate of the bulk flow in a volume of radii 150− 200 h− 1 Mpc using the
minimum variance method with data from the CosmicFlows-4 (CF4) catalogue. The addition …

We train graph neural networks to perform field-level likelihood-free inference using galaxy
catalogs from state-of-the-art hydrodynamic simulations of the CAMELS project. Our models …

Abstract 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 …

We decompose Pantheon+ Type Ia supernovae (SN) in hemispheres on the sky finding
angular variations up to 4 km/s/Mpc, corresponding to a statistical significance up to 1.9 σ, in …

For over a decade there have been contradictory claims in the literature about whether the
local bulk flow motion of galaxies is consistent or in tension with the ΛCDM model. While it …

Galaxy peculiar velocities provide an integral source of cosmological information that can be
harnessed to measure the growth rate of large-scale structure and constrain possible …

We describe the target selection and characteristics of the DESI Peculiar Velocity Survey,
the largest survey of peculiar velocities (PVs) using both the fundamental plane (FP) and the …
