Synthetic Galaxy Images and Spectra from the Illustris Simulation
Paul Torrey, Gregory F. Snyder, Mark Vogelsberger +10
We present our methods for generating a catalog of 7,000 synthetic images and 40,000 integrated spectra of redshift z = 0 galaxies from the Illustris Simulation. The mock data prod…
The Formation of Massive, Compact Galaxies at z=2 in the Illustris Simulation
Sarah Wellons, Paul Torrey, Chung-Pei Ma +13
Massive, quiescent galaxies at high redshift have been found to be considerably more compact than galaxies of similar mass in the local universe. How these compact galaxies formed…
The colors of satellite galaxies in the Illustris Simulation
Laura V. Sales, Mark Vogelsberger, Shy Genel +8
Observationally, the fraction of blue satellite galaxies decreases steeply with host halo mass, and their radial distribution around central galaxies is significantly shallower in…
The impact of feedback on cosmological gas accretion
Dylan Nelson, Shy Genel, Mark Vogelsberger +4
We investigate how the way galaxies acquire their gas across cosmic time in cosmological hydrodynamic simulations is modified by a comprehensive physical model for baryonic feedbac…
The star formation main sequence and stellar mass assembly of galaxies in the Illustris simulation
Martin Sparre, Christopher C. Hayward, Volker Springel +6
Understanding the physical processes that drive star formation is a key challenge for galaxy formation models. In this article we study the tight correlation between the star forma…
The Illustris simulation: the evolving population of black holes across cosmic time
Debora Sijacki, Mark Vogelsberger, Shy Genel +5
We study the properties of black holes and their host galaxies across cosmic time in the Illustris simulation. Illustris is a large scale cosmological hydrodynamical simulation whi…
