Here we collect the AGORA common initial conditions (ICs), examples of common analysis yt scripts used in the Project, the galaxy simulation snapshots produced by AGORA, and more. Consider joining the Collaboration with no obligation, especially if you want to learn more about the AGORA common ICs and analysis scripts used in the Project. Simply send an email to the Project coordinator. Contact us if you have any other question, too!

COMMON PHYSICS PACKAGE
COMMON PHYSICS PACKAGE
● To ensure consistent comparison across codes, AGORA simulations use the common physics library GRACKLE, which features equilibrium/non-equilibrium primordial chemistry and cooling, tabulated metal cooling, and a metagalactic UV background. We also adopt several other common physics prescriptions such as Jeans pressure floor, star formation, and metal production. [Read more]
□ Described in the AGORA Flagship Paper (Section 3; ADS, arXiv), in Paper II (Section 3; ADS, arXiv) and in Paper III (Section 3; ADS, arXiv)
□ Key software required: GRACKLE by Britton Smith et al. (visit this page for instructions to build the library and to implement the backend within a simulation code)
□ For more information on GRACKLE (e.g., method paper, user group) visit Workspace, then Home+FAQs → Key Softwares (membership required)
□ More information by AGORA Working Group I: Workspace → Working Group I (membership required)
COMMON ANALYSIS PLATFORM
COMMON ANALYSIS PLATFORM
● To allow consistent comparison independent of analysis tools used, we build an analysis toolkit on a common platform YT, which seamlessly reads the snapshots from all the participating code groups in AGORA. [Read more]
□ Described in the AGORA Flagship Paper (Section 4.2; ADS, arXiv)
□ Example scripts used to create figures and plots in AGORA Papers by Ji-hoon Kim and AGORA Working Group IV
□ Key software required (I): YT by Matthew Turk et al.
□ Key software required (II): TRIDENT by Cameron Hummels et al.
□ For more information on YT and TRIDENT (e.g., method paper, user group, example ipython notebooks) visit Workspace, then Home+FAQs → Key Softwares (membership required)
□ More information by AGORA Working Group IV Workspace → Working Group IV (membership required)
ISOLATED DISK GALAXY SIMULATION SNAPSHOTS
ISOLATED DISK GALAXY SIMULATION SNAPSHOTS
● We provide the isolated disk galaxy simulation snapshots (on FlatHUB) by 9 code groups introduced in AGORA Paper II (ADS, arXiv). [Read more]
□ Also available on Google Drive: isolated disk galaxy simulation snapshots
□ Described in its accompanying release note (arXiv, local/high-res) and in AGORA Paper II (Section 6; ADS, arXiv)
□ More tests by AGORA Working Groups II+V: Workspace → Paper Group "Disk" (membership required)
COSMOLOGICAL GALAXY SIMULATION SNAPSHOTS
COSMOLOGICAL GALAXY SIMULATION SNAPSHOTS
● We provide the cosmological MW-sized galaxy simulation snapshots (on FlatHUB) by 7 code groups introduced in AGORA Paper III (ADS, arXiv). [Read more]
□ Described in its accompanying release note (arXiv, local/high-res) and in AGORA Paper III (Sections 5 & 6; ADS, arXiv)
□ In the released data, we include 14 snapshots from each code at the integer redshifts between 15 and 2, plus the ones at z=1 and 0, when available. You can find the snapshot number (included in the snapshot filename) corresponding to each specific redshift in the table below. Together with the snapshots data we also released several metadata files such as halo centers and merger trees. For more information, please visit the dedicated FlatHUB page above!
