The IllustrisTNG simulations: public data release

摘要: We present the full public release of all data from TNG100 and TNG300 simulations IllustrisTNG project. is a suite large volume, cosmological, gravo-magnetohydrodynamical run with moving-mesh code Arepo. TNG includes comprehensive model for galaxy formation physics, each simulation self-consistently solves coupled evolution dark matter, cosmic gas, luminous stars, supermassive black holes early time to day, $z=0$ . Each flagship runs—TNG50, TNG100, TNG300—are accompanied by halo/subhalo catalogs, merger trees, lower-resolution dark-matter only counterparts, available 100 snapshots. discuss scientific numerical cautions caveats relevant when using TNG. The volume now directly accessible online ∼750 TB, including 1200 snapshots ∼80,000 high time-resolution subbox This will increase ∼1.1 PB future TNG50. Data access analysis examples are in IDL, Python, Matlab. describe improvements new functionality web-based API, on-demand visualization galaxies halos, exploratory plotting scaling relations other relationships between galactic halo properties, JupyterLab interface. provides an online, browser-based, near-native platform enabling user computation local data, alleviating need download datasets.
