Our Galaxy, the Milky Way, is a benchmark for understanding disk galaxies. It is the only
galaxy whose formation history can be studied using the full distribution of stars from faint …

Weak gravitational lensing of background galaxies provides a direct probe of the projected
matter distribution in and around galaxy clusters. Here, we present a self-contained …

We present an updated version of the hmcode augmented halo model that can be used to
make accurate predictions of the non-linear matter power spectrum over a wide range of …

We introduce the Uchuu suite of large high-resolution cosmological N-body simulations. The
largest simulation, named Uchuu, consists of 2.1 trillion (12 8003) dark matter particles in a …

This paper introduces C olossus, a public, open-source python package for calculations
related to cosmology, the large-scale structure (LSS) of matter in the universe, and the …

We use the age–metallicity distribution of 96 Galactic globular clusters (GCs) to infer the
formation and assembly history of the Milky Way (MW), culminating in the reconstruction of …

Axions are some of the best motivated particles beyond the Standard Model. We show how
the attractive self-interactions of dark matter (DM) axions over a broad range of masses, from …

The relation between halo mass, M, and concentration, c, is a critical component in our
understanding of the structure of dark matter halos. While numerous models for this relation …

We use a suite of cosmological simulations to study the mass–concentration–redshift
relation, c (M, z), of dark matter haloes. Our simulations include standard Λ-cold dark matter …

The boundaries of cold dark matter halos are commonly defined to enclose a density
contrast Δ relative to a reference (mean or critical) density. We argue that a more physical …
