Dylan Nelson,Annalisa Pillepich,Shy Genel,Shy Genel,Mark Vogelsberger,Volker Springel,Volker Springel,Paul Torrey,Paul Torrey,Vicente Rodriguez-Gomez,Debora Sijacki,Gregory F. Snyder,Brendan F. Griffen,Federico Marinacci,Laura Blecha,Laura V. Sales,Dandan Xu,Lars Hernquist +17 more
TL;DR: The full public release of all data from the Illustris simulation project is presented, including the flagship Illustris-1 run, and a comprehensive, web-based API which allows programmatic access to search and data processing tasks is released.
Journal ArticleDOI

E. van den Bosch,Hans-Walter Rix,Mariya Lyubenova,Mariya Lyubenova,Jesús Falcón-Barroso,Jesús Falcón-Barroso,Marie Martig,Marie Martig,Shude Mao,Shude Mao,Dandan Xu,Yunpeng Jin,Aura Obreja,Aura Obreja,Robert J. J. Grand,Robert J. J. Grand,Aaron A. Dutton,Andrea V. Macciò,Facundo A. Gómez,Jakob Walcher,Rubén García-Benito,Stefano Zibetti,Sebastián F. Sánchez +25 more
TL;DR: In this article, the authors derived the orbit-circularity distribution as a function of galaxy mass and its volume-averaged total distribution for a well-defined, large sample of 300 nearby galaxies.
Journal ArticleDOI
Early-type galaxy density profiles from IllustrisTNG - I. Galaxy correlations and the impact of baryons
Yunchong Wang,Yunchong Wang,Mark Vogelsberger,Dandan Xu,Shude Mao,Shude Mao,Volker Springel,Hui Li,David J. Barnes,Lars Hernquist,Annalisa Pillepich,Federico Marinacci,Ruediger Pakmor,Rainer Weinberger,Paul Torrey +14 more
TL;DR: In this article, the authors explore the isothermal total density profiles of early-type galaxies (ETGs) in the IllustrisTNG simulation, revealing that the ETG dark matter halos are well-described by steeper-than-NFW profiles, and they are steeper in the full physics (FP) run than their counterparts in the dark matter only (DMO) run.
Journal ArticleDOI
Evaluating the ability of triaxial Schwarzschild modelling to estimate properties of galaxies from the Illustris simulation
Yunpeng Jin,Ling Zhu,Richard J. Long,Richard J. Long,Richard J. Long,Shude Mao,Shude Mao,Dandan Xu,Hongyu Li,Glenn van de Ven,Glenn van de Ven +10 more
TL;DR: In this paper, the authors evaluate the capabilities of Schwarzschild's orbit-superposition method by applying it to galaxies from the large scale, high resolution Illustris simulation, and assess model estimates of various galaxy properties, covering mass profiles, intrinsic shapes, stellar orbit distributions and velocity anisotropies.
Journal ArticleDOI
Redshift evolution of the Fundamental Plane relation in the IllustrisTNG simulation
S. L. Lu,Dandan Xu,Yunchong Wang,Shude Mao,Shude Mao,Junqiang Ge,Volker Springel,Yuan Wang,Mark Vogelsberger,Jill Naiman,Jill Naiman,Lars Hernquist +11 more
TL;DR: In this article, the authors investigated the fundamental plane evolution of early-type galaxies in the IllustrisTNG-100 simulation (TNG100) from redshift $z=0$ to $z-2$ and found that a tight plane relation already exists as early as $z = 2.
