Spurred by rich, multiwavelength observations and enabled by new simulations, ranging
from cosmological to subparsec scales, the past decade has seen major theoretical …

Neutral-atomic and molecular outflows are a common occurrence in galaxies, near and far.
They operate over the full extent of their galaxy hosts, from the innermost regions of galactic …

One of the key open questions in extragalactic astronomy is what stops star formation in
galaxies. While it is clear that the cold gas reservoir, which fuels the formation of new stars …

We present a novel analytic framework to model the steady-state structure of multiphase
galactic winds comprised of a hot, volume-filling component and a cold, clumpy component …

We use the high-resolution TNG50 cosmological magnetohydrodynamical simulation to
explore the properties and origin of cold circumgalactic medium (CGM) gas around massive …

Both absorption and emission-line studies show that cold gas around galaxies is commonly
outflowing at speeds of several hundred km s− 1. This observational fact poses a severe …

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 …

Galactic halo gas traces inflowing star-formation fuel and feedback from a galaxy's disk and
is therefore crucial to our understanding of galaxy evolution. In this review, we summarize …

The existence of fast moving, cold gas ubiquitously observed in galactic winds is
theoretically puzzling, since the destruction time of cold gas is much smaller than its …

To better understand the nature of the multiphase material found in outflowing galaxies, we
study the evolution of cold clouds embedded in flows of hot and fast material. Using a suite …
