Numerical simulations have become a major tool for understanding galaxy formation and
evolution. Over the decades the field has made significant progress. It is now possible to …

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 …

We demonstrate a novel technology that combines the power of the multi-object
spectrograph with the spatial multiplex advantage of an integral field spectrograph (IFS). The …

We present Keck/LRIS spectra of over 200 galaxies with well-determined redshifts between
0.4 and 1.4. We combine new measurements of near-ultraviolet, low-ionization absorption …

Magnetic fields are known to be dynamically important in the interstellar medium of our own
Galaxy, and they are ubiquitously observed in diffuse gas in the haloes of galaxies and …

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 …

Motivated by a new wave of kinematical tracers in the outer regions of early-type galaxies
(ellipticals and lenticulars), we re-examine the role of angular momentum in galaxies of all …

A suite of vast stellar surveys map** the Milky Way, culminating in the Gaia mission, is
revolutionizing the empirical information about the distribution and properties of stars in the …

Using a set of 15 high-resolution magnetohydrodynamic cosmological simulations of Milky
Way formation, we investigate the origin of the baryonic material found in stars at redshift …

We construct an analytic phenomenological model for extended warm/hot gaseous coronae
of L* galaxies. We consider UV O vi Cosmic Origins Spectrograph (COS)-Halos absorption …
