Author(s): Boylan-Kolchin, M; Weisz, DR; Bullock, JS; Cooper, MC | Abstract: © 2016 The Authors. Near-field cosmology - using detailed observations of the Local Group and its environs to study wide-ranging questions in galaxy formation and dark matter physics - has become a mature and rich field over the past decade. There are lingering concerns, however, that the relatively small size of the present-day Local Group (~2Mpc diameter) imposes insurmountable samplevariance uncertainties, limiting… 
Environmental quenching of low-mass field galaxies.
The role of environmental processes in quenching star formation within the nearby field is investigated and a quenched fraction - due solely to environmental effects - of ~0.52 ± 0.26 is predicted within 1 < R/R vir < 2 of the Milky Way and M31.
The suppression of star formation on the smallest scales: what role does environment play?
The predominantly ancient stellar populations observed in the lowest-mass galaxies (i.e. ultra-faint dwarfs) suggest that their star formation was suppressed by reionization. Most of the well-studied
Globular clusters in high-redshift dwarf galaxies: a case study from the Local Group.
We present the reconstructed evolution of rest-frame ultraviolet (UV) luminosities of the most massive Milky Way dwarf spheroidal satellite galaxy, Fornax, and its five globular clusters (GCs) across
Reconstructing the Last Major Merger of the Milky Way with the H3 Survey
Several lines of evidence suggest that the Milky Way underwent a major merger at z ∼ 2 with the Gaia-Sausage-Enceladus (GSE) galaxy. Here we use H3 Survey data to argue that GSE entered the Galaxy on
Exploring simulated early star formation in the context of the ultrafaint dwarf galaxies
Ultrafaint dwarf galaxies (UFDs) are typically assumed to have simple, stellar populations with star formation ending at reionization. Yet as the observations of these galaxies continue to improve,
Evidence from the H3 Survey That the Stellar Halo Is Entirely Comprised of Substructure
In the $\Lambda$CDM paradigm the Galactic stellar halo is predicted to harbor the accreted debris of smaller systems. To identify these systems, the H3 Spectroscopic Survey, combined with $Gaia$, is
The ISLAndS project II: The Lifetime Star Formation Histories of Six Andromeda dSphs
The Initial Star formation and Lifetimes of Andromeda Satellites (ISLAndS) project uses Hubble Space Telescope imaging to study a representative sample of six Andromeda dSph satellite companion
Semi-analytic forecasts for JWST – IV. Implications for cosmic reionization and LyC escape fraction
Galaxies forming in low-mass haloes are thought to be primarily responsible for reionizing the Universe during the first billion years after the big bang. Yet, these haloes are extremely
Selecting ultra-faint dwarf candidate progenitors in cosmological N-body simulations at high redshifts
The smallest satellites of the Milky Way ceased forming stars during the epoch of reionization and thus provide archaeological access to galaxy formation at $z>6$. Numerical studies of these
The globular cluster-dark matter halo connection.
Making predictions for the fraction of accreted versus in situ GCs in the local Universe and for descendants of systems at the halo mass threshold of GC formation (dwarf galaxies) are explored.


ELVIS: Exploring the Local Volume in Simulations
We introduce a set of high-resolution dissipationless simulations that model the Local Group (LG) in a cosmological context: Exploring the Local Volume in Simulations (ELVIS). The suite contains 48
Push it to the limit: Local Group constraints on high-redshift stellar mass functions for M⋆ ≥ 105 M⊙
Author(s): Graus, AS; Bullock, JS; Boylan-Kolchin, M; Weisz, DR | Abstract: © 2015 The Authors. We constrain the evolution of the galaxy stellar mass function from 2 2 × 105M⊙ at z = 0). The most

This paper presents the Hubble Ultra Deep Field (HUDF), a 1 million s exposure of an 11 arcmin2 region in the southern sky with the Advanced Camera for Surveys on the Hubble Space Telescope using
The Local Group as a time machine: studying the high-redshift Universe with nearby galaxies
We infer the UV luminosities of Local Group galaxies at early cosmic times ($z \sim 2$ and $z \sim 7$) by combining stellar population synthesis modeling with star formation histories derived from
The installation of the Wide Field Camera 3 (WFC3) on the Hubble Space Telescope (HST) will revolutionize the study of high-redshift galaxy populations. Initial observations of the HST Ultra Deep
How to zoom: bias, contamination and Lagrange volumes in multimass cosmological simulations
We perform a suite of multimass cosmological zoom simulations of individual dark matter halos and explore how to best select Lagrangian regions for resimulation without contaminating the halo of
ΛCDM-based Models for the Milky Way and M31. I. Dynamical Models
We apply standard disk formation theory with adiabatic contraction within cuspy halo models predicted by the standard cold dark matter (?CDM) cosmology. The resulting models are confronted with the

Ellipsoidal collapse and an improved model for the number and spatial distribution of dark matter haloes
The Press–Schechter, excursion set approach allows one to make predictions about the shape and evolution of the mass function of bound objects. The approach combines the assumption that objects
