Introducing the Illustris Project: simulating the coevolution of dark and visible matter in the Universe
Mark Vogelsberger,Shy Genel,Volker Springel,Volker Springel,Paul Torrey,Debora Sijacki,Dandan Xu,Gregory F. Snyder,Dylan Nelson,Lars Hernquist +9 more
TL;DR: The Illustris Project as mentioned in this paper is a series of large-scale hydrodynamical simulations of galaxy formation, which includes primordial and metal-line cooling with self-shielding corrections, stellar evolution, stellar feedback, gas recycling, chemical enrichment, supermassive black hole growth, and feedback from active galactic nuclei.

Properties of galaxies reproduced by a hydrodynamic simulation
Mark Vogelsberger,Shy Genel,Volker Springel,Volker Springel,Paul Torrey,Debora Sijacki,Dandan Xu,Gregory F. Snyder,Simeon Bird,Dylan Nelson,Lars Hernquist +10 more
TL;DR: A simulation that starts 12 million years after the Big Bang, and traces 13 billion years of cosmic evolution with 12 billion resolution elements in a cube of 106.5 megaparsecs a side yields a reasonable population of ellipticals and spirals, reproduces the observed distribution of galaxies in clusters and characteristics of hydrogen on large scales, and at the same time matches the ‘metal’ and hydrogen content of galaxies on small scales.

Introducing the Illustris Project: the evolution of galaxy populations across cosmic time
Shy Genel,Mark Vogelsberger,Volker Springel,Volker Springel,Debora Sijacki,Dylan Nelson,Greg Snyder,Vicente Rodriguez-Gomez,Paul Torrey,Lars Hernquist +9 more
TL;DR: In this article, the authors present an overview of galaxy evolution across cosmic time in the Illustris Simulation, an N-body/hydrodynamical simulation that evolves 2*1820^3 resolution elements in a (106.5Mpc)^3 box from cosmological initial conditions down to z=0 using the AREPO moving-mesh code.

Mark Vogelsberger,Shy Genel,Debora Sijacki,Paul Torrey,Volker Springel,Volker Springel,Lars Hernquist +6 more
TL;DR: In this article, a new comprehensive model of the physics of galaxy formation designed for large-scale hydrodynamical simulations of structure formation using the moving mesh code AREPO is presented.

The merger rate of galaxies in the Illustris simulation: a comparison with observations and semi-empirical models
Vicente Rodriguez-Gomez,Shy Genel,Shy Genel,Mark Vogelsberger,Debora Sijacki,Annalisa Pillepich,Laura V. Sales,Laura V. Sales,Paul Torrey,Paul Torrey,Greg Snyder,Dylan Nelson,Volker Springel,Volker Springel,Chung-Pei Ma,Lars Hernquist +15 more
TL;DR: In this paper, the authors constructed merger trees for galaxies in the Illustris simulation by directly tracking the baryonic content of subhaloes and used them to calculate the galaxy-galaxy merger rate as a function of descendant stellar mass.
