Efficacy of early stellar feedback in low gas surface density environments
Rahul Kannan, Federico Marinacci, Christine M. Simpson +2
We present a suite of high resolution radiation hydrodynamic simulations of a small patch () of the inter-stellar medium (ISM) performed with Arepo-RT, with the ai…
The star-formation activity of IllustrisTNG galaxies: main sequence, UVJ diagram, quenched fractions, and systematics
Martina Donnari, Annalisa Pillepich, Dylan Nelson +6
We select galaxies from the IllustrisTNG hydrodynamical simulations ( at ) and characterize the shapes and evolutions of their UVJ and star-format…
The IllustrisTNG Simulations: Public Data Release
Dylan Nelson, Volker Springel, Annalisa Pillepich +11
We present the full public release of all data from the TNG50, TNG100 and TNG300 simulations of the IllustrisTNG project. IllustrisTNG is a suite of large volume, cosmological, gra…
Jellyfish galaxies with the IllustrisTNG simulations: I. Gas-stripping phenomena in the full cosmological context
Kiyun Yun, Annalisa Pillepich, Elad Zinger +8
We use IllustrisTNG, a suite of gravity and MHD simulations, to study the demographics and properties of jellyfish galaxies in the full cosmological context. By jellyfish galaxies,…
Zooming in on accretion - II. Cold Circumgalactic Gas Simulated with a super-Lagrangian Refinement Scheme
Joshua Suresh, Dylan Nelson, Shy Genel +2
In this study we explore the complex multi-phase gas of the circumgalactic medium (CGM) surrounding galaxies. We propose and implement a novel, super-Lagrangian 'CGM zoom' scheme i…
Early-type galaxy density profiles from IllustrisTNG: I. Galaxy correlations and the impact of baryons
Yunchong Wang, Mark Vogelsberger, Dandan Xu +10
We explore the isothermal total density profiles of early-type galaxies (ETGs) in the IllustrisTNG simulation. For the selected 559 ETGs at with stellar mass $10^{10.7}\mat…
Atomic hydrogen in IllustrisTNG galaxies: the impact of environment parallelled with local 21-cm surveys
Adam R. H. Stevens, Benedikt Diemer, Claudia del P. Lagos +8
We investigate the influence of environment on the cold-gas properties of galaxies at z=0 within the TNG100 cosmological, magnetohydrodynamic simulation, part of the IllustrisTNG s…
Shape of Dark Matter Haloes in the Illustris Simulation: Effects of Baryons
Kunting Eddie Chua, Annalisa Pillepich, Mark Vogelsberger +1
We study the effect of baryonic processes on the shapes of dark matter (DM) haloes from Illustris, a suite of hydrodynamical (Illustris) and DM-only (Illustris-Dark) cosmological s…
The optical morphologies of galaxies in the IllustrisTNG simulation: a comparison to Pan-STARRS observations
Vicente Rodriguez-Gomez, Gregory F. Snyder, Jennifer M. Lotz +12
We have generated synthetic images of 27,000 galaxies from the IllustrisTNG and the original Illustris hydrodynamic cosmological simulations, designed to match Pan-STARRS obs…
Linking galaxy structural properties and star formation activity to black hole activity with IllustrisTNG
Melanie Habouzit, Shy Genel, Rachel S. Somerville +11
We study the connection between active galactic nuclei (AGN) and their host galaxies through cosmic time in the large-scale cosmological IllustrisTNG simulations. We first compare…
Automated Distant Galaxy Merger Classifications from Space Telescope Images using the Illustris Simulation
Gregory F. Snyder, Vicente Rodriguez-Gomez, Jennifer M. Lotz +5
We present image-based evolution of galaxy mergers from the Illustris cosmological simulation at 12 time-steps over 0.5 < z < 5. To do so, we created approximately one million synt…
A Quantification of the Butterfly Effect in Cosmological Simulations and Implications for Galaxy Scaling Relations
Shy Genel, Greg L. Bryan, Volker Springel +7
We study the chaotic-like behavior of cosmological simulations by quantifying how minute perturbations grow over time and manifest as macroscopic differences in galaxy properties.…
Modeling the atomic-to-molecular transition in cosmological simulations of galaxy formation
Benedikt Diemer, Adam R. H. Stevens, John C. Forbes +10
Large-scale cosmological simulations of galaxy formation currently do not resolve the densities at which molecular hydrogen forms, implying that the atomic-to-molecular transition…
Formation of a Malin 1 analogue in IllustrisTNG by stimulated accretion
Qirong Zhu, Dandan Xu, Massimo Gaspari +13
The galaxy Malin 1 contains the largest stellar disk known but the formation mechanism of this structure has been elusive. In this paper, we report a Malin 1 analogue in the 100 Mp…
Enhancing AGN efficiency and cool-core formation with anisotropic thermal conduction
David J. Barnes, Rahul Kannan, Mark Vogelsberger +10
Understanding how baryonic processes shape the intracluster medium (ICM) is of critical importance to the next generation of galaxy cluster surveys. However, most models of structu…
