The Heavy Metal Survey: Star Formation Constraints and Dynamical Masses of 21 Massive Quiescent Galaxies at z = 1.3–2.3

The Astrophysical Journal
In this paper, we present the Heavy Metal Survey, which obtained ultradeep medium-resolution spectra of 21 massive quiescent galaxies at 1.3 < z < 2.3 with Keck/LRIS and MOSFIRE.

Star Formation for Predictive Primordial Galaxy Formation

, 2015
The elegance of inflationary cosmology and cosmological perturbation theory ends with the formation of the first stars and galaxies, the initial sources of light that launched the phenomenologically rich process of cosmic reionization. Here we review the

Locally Biased Galaxy Formation and Large Scale Structure [PDF]

, 1998
We examine the influence of the morphology-density(MD) relation and a wide range of simple models for biased galaxy formation on statistical measures of large scale structure.

nIFTy cosmology: comparison of galaxy formation models [PDF]

, 2015
We present a comparison of 14 galaxy formation models: 12 different semi-analytical models and 2 halo occupation distribution models for galaxy formation based upon the same cosmological simulation and merger tree information derived from it.

Gas-Rich Companions of Isolated Galaxies [PDF]

, 1999
We have used the VLA to search for gaseous remnants of the galaxy formation process around six extremely isolated galaxies. We found two distinct HI clouds around each of two galaxies in our sample (UGC 9762 & UGC 11124).

The EAGLE simulations of galaxy formation: the importance of the hydrodynamics scheme [PDF]

, 2015
We present results from a subset of simulations from the "Evolution and Assembly of GaLaxies and their Environments" (EAGLE) suite in which the formulation of the hydrodynamics scheme is varied.

Diffuse Light in Milky Way–like Haloes

The Astrophysical Journal Letters
We investigate the diffuse light (DL) content of dark matter haloes in the mass range $11.5\leqslant \mathrm{log}{M}_{\mathrm{halo}}\leqslant 13$ , a range that also includes the dark matter halo of the Milky Way, taking advantage of a state-of-the-art ...

Mapping Global Star Formation in the Interacting Galaxy Pair Arp32 [PDF]

, 2008
A multi-wavelength set of photometric data including UV (GALEX), optical, near-IR, infrared (Spitzer) and radio (VLA 20cm) images and spectroscopic observations are used to map the dust-obscured and unobscured star formation in the galaxy pair Arp 32 ...

How do galaxies get their baryons?

, 2011
Understanding how galaxies obtain baryons, their stars and gas, over cosmic time is traditionally approached in two different ways - theoretically and observationally.
