Descendants of the first stars: the distinct chemical signature of second generation stars
Tilman Hartwig, Naoki Yoshida, Mattis Magg +9
Extremely metal-poor (EMP) stars in the Milky Way (MW) allow us to infer the properties of their progenitors by comparing their chemical composition to the metal yields of the firs…
Predicting the locations of possible long-lived low-mass first stars: Importance of satellite dwarf galaxies
Mattis Magg, Tilman Hartwig, Bhaskar Agarwal +4
The search for metal-free stars has so far been unsuccessful, proving that if there are surviving stars from the first generation, they are rare, they have been polluted, or we hav…
Tracing the first stars and galaxies of the Milky Way
Brendan F. Griffen, Gregory A. Dooley, Alexander P. Ji +3
We use 30 high-resolution dark matter halos of the simulation suite to probe the first stars and galaxies of Milky Way-mass systems. We quantify the environment of th…
An observer's guide to the (Local Group) dwarf galaxies: predictions for their own dwarf satellite populations
Gregory A. Dooley, Annika H. G. Peter, Tianyi Yang +3
A recent surge in the discovery of new ultrafaint dwarf satellites of the Milky Way has inspired the idea of searching for faint satellites, $10^3\, \mathrm{M_{\odot}} < M_* < 10^6…
The role of mergers and halo spin in shaping galaxy morphology
Vicente Rodriguez-Gomez, Laura V. Sales, Shy Genel +10
Mergers and the spin of the dark matter halo are factors traditionally believed to determine the morphology of galaxies within a CDM cosmology. We study this hypothesis by consi…
Constraining ultra-compact dwarf galaxy formation with galaxy clusters in the local universe
Joel Pfeffer, Michael Hilker, Holger Baumgardt +1
We compare the predictions of a semi-analytic model for ultra-compact dwarf galaxy (UCD) formation by tidal stripping to the observed properties of globular clusters (GCs) and UCDs…
The Caterpillar Project: A Large Suite of Milky Way Sized Halos
Brendan F. Griffen, Alexander P. Ji, Gregory A. Dooley +4
We present the largest number of Milky Way sized dark matter halos simulated at very high mass ( M/particle) and temporal resolution (5 Myrs/snapshot) don…
An analysis of the evolving comoving number density of galaxies in hydrodynamical simulations
Paul Torrey, Sarah Wellons, Francisco Machado +9
The cumulative comoving number-density of galaxies as a function of stellar mass or central velocity dispersion is commonly used to link galaxy populations across different epochs.…
The Illustris Simulation: Public Data Release
Dylan Nelson, Annalisa Pillepich, Shy Genel +12
We present the full public release of all data from the Illustris simulation project. Illustris is a suite of large volume, cosmological hydrodynamical simulations run with the mov…
Contribution of stripped nuclear clusters to globular cluster and ultra-compact dwarf galaxy populations
Joel Pfeffer, Brendan F. Griffen, Holger Baumgardt +1
We use the Millennium II cosmological simulation combined with the semi-analytic galaxy formation model of Guo et al. (2011) to predict the contribution of galactic nuclei formed b…
The Effects of Varying Cosmological Parameters on Halo Substructure
Gregory A. Dooley, Brendan F. Griffen, Phillip Zukin +4
We investigate how different cosmological parameters, such as those delivered by the WMAP and Planck missions, affect the nature and evolution of dark matter halo substructure. We…
The inhomogenous reionization of the inter-galactic medium by metal-poor globular clusters
B. F. Griffen, M. J. Drinkwater, Ilian T. Iliev +2
We present detailed radiative transfer simulations of the reionization history of the Milky Way by metal-poor globular clusters. We identify potential metal-poor globular cluster c…
Globular Cluster Formation Within The Aquarius Simulation
B. F. Griffen, M. J. Drinkwater, P. A. Thomas +2
The Aquarius project is the first simulation that can resolve the full mass range of potential globular cluster formation sites. With a particle mass …
