Observations that resolve nearby galaxies into individual regions across multiple phases of
the gas–star formation feedback “matter cycle” have provided a sharp new view of molecular …

Over the past decade, increasingly robust estimates of the dense molecular gas content in
galaxy populations between redshift z= 0 and the peak of cosmic galaxy/star formation (z∼ …

Star clusters stand at the intersection of much of modern astrophysics: the ISM, gravitational
dynamics, stellar evolution, and cosmology. Here, we review observations and theoretical …

We present a unified description of the scenario of global hierarchical collapse (GHC). GHC
constitutes a flow regime of (non-homologous) collapses within collapses, in which all …

This paper describes the open-source code Enzo, which uses block-structured adaptive
mesh refinement to provide high spatial and temporal resolution for modeling astrophysical …

We introduce a new model for the structure and evolution of the gas in galactic discs. In the
model the gas is in vertical pressure and energy balance. Star formation feedback injects …

The role of turbulence and magnetic fields is studied for star formation in molecular clouds.
We derive and compare six theoretical models for the star formation rate (SFR)—the …

We use high-resolution simulations of isolated dwarf galaxies to study the physics of dark
matter cusp-core transformations at the edge of galaxy formation: M 200= 107–109 M⊙. We …

Winds from massive stars have velocities of 1000 km s− 1 or more and produce hot, high-
pressure gas when they shock. We develop a theory for the evolution of bubbles driven by …

Giant molecular clouds (GMCs) are the sites of star formation and stellar feedback in
galaxies. Their properties set the initial conditions for star formation and their lifecycles …
