The stellar mass assembly of galaxies in the Illustris simulation: growth by mergers and the spatial distribution of accreted stars
Vicente Rodriguez-Gomez, Annalisa Pillepich, Laura V. Sales +9
We use the Illustris simulation to study the relative contributions of in situ star formation and stellar accretion to the build-up of galaxies over an unprecedentedly wide range o…
On the Assembly of Dwarf Galaxies in Clusters and their Efficient Formation of Globular Clusters
Pouria A. Mistani, Laura V. Sales, Annalisa Pillepich +6
Galaxy clusters contain a large population of low mass dwarf elliptical galaxies whose exact origin is unclear: their colors, structural properties and kinematics differ substantia…
Sussing Merger Trees: A proposed Merger Tree data format
Peter A. Thomas, Julian Onions, Dylan Tweed +13
We propose a common terminology for use in describing both temporal merger trees and spatial structure trees for dark-matter halos. We specify a unified data format in HDF5 and pro…
Modeling Galactic Conformity with the Color-Halo Age Relation in the Illustris Simulation
Aaron D. Bray, Annalisa Pillepich, Laura V. Sales +9
Comparisons between observational surveys and galaxy formation models find that the mass of dark matter haloes can largely explain galaxies' stellar mass. However, it remains uncer…
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 diverse evolutionary paths of simulated high-z massive, compact galaxies to z=0
Sarah Wellons, Paul Torrey, Chung-Pei Ma +6
Massive quiescent galaxies have much smaller physical sizes at high redshift than today. The strong evolution of galaxy size may be caused by progenitor bias, major and minor merge…
Galactic Angular Momentum in the Illustris Simulation: Feedback and the Hubble Sequence
Shy Genel, S. Michael Fall, Lars Hernquist +5
We study the stellar angular momentum of thousands of galaxies in the Illustris cosmological simulation, which captures gravitational and gas dynamics within galaxies, as well as f…
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…
The merger rate of galaxies in the Illustris Simulation: a comparison with observations and semi-empirical models
Vicente Rodriguez-Gomez, Shy Genel, Mark Vogelsberger +9
We have constructed merger trees for galaxies in the Illustris Simulation by directly tracking the baryonic content of subhalos. These merger trees are used to calculate the galaxy…
