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 …

The diffuse light that spreads through groups and clusters of galaxies is made of free-floating
stars not bound to any galaxy. This is known as the intracluster light (ICL) and holds …

The IllustrisTNG project is a new suite of cosmological magnetohydrodynamical simulations
of galaxy formation performed with the arepo code and updated models for feedback …

The inefficiency of star formation in massive elliptical galaxies is widely believed to be
caused by the interactions of an active galactic nucleus (AGN) with the surrounding gas …

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 …

Globular clusters (GCs) formed when the Milky Way experienced a phase of rapid assembly.
We use the wealth of information contained in the Galactic GC population to quantify the …

We present an overview of galaxy evolution across cosmic time in the Illustris simulation.
Illustris is an N-body/hydrodynamical simulation that evolves 2× 18203 resolution elements …

Abstract Knowledge of the ages of the stars formed over a galaxy's lifetime is fundamental to
an understanding of its formation and evolution. However, stellar ages are difficult to obtain …

We present the full public release of all data from the Illustris simulation project. Illustris is a
suite of large volume, cosmological hydrodynamical simulations run with the moving-mesh …

We use the Illustris simulation to study the relative contributions of in situ star formation and
stellar accretion to the build-up of galaxies over an unprecedentedly wide range of masses …
