The AGORA high-resolution galaxy simulations comparison project: CosmoRun data release

TL;DR

This paper announces the public release of high-resolution cosmological simulation data of Milky Way-sized galaxies, generated by eight different numerical codes, covering various redshifts for comparative galaxy formation studies.

Contribution

It provides the first comprehensive public dataset from the AGORA Cosmorun simulations, enabling cross-code comparison and validation of galaxy formation models.

Findings

Data covers multiple redshifts from z=8 to z=0

Includes outputs from eight widely used simulation codes

Provides detailed halo and merger information

Abstract

The AGORA Cosmorun (arXiv:2106.09738) is a set of hydrodynamical cosmological zoom-in simulations carried out within the AGORA High-resolution Galaxy Simulations Comparison Project (arXiv:1308.2669,arXiv:1610.03066). These simulations show the formation and evolution of a Milky Way-sized galaxy using eight of the most widely used numerical codes in the community (Art-I, Enzo, Ramses, Changa, Gadget-3, Gear, Gizmo, and Arepo). In this short report, we describe the public release of the raw output data from all of these simulations at z = 8, 7, 6, 5, 4, 3, 2 (plus at z=1, 0 when available), and several metadata files containing the halo centers, virial quantities, and merger trees. The data from even thinner timesteps will be released as soon as the upcoming collaboration papers (VII-IX) are submitted and accepted.
