摘要:

作为AGORA高分辨率星系模拟比较项目(Kim et al. 2014,2016)的一部分,我们使用9种在数值星系形成社区中广泛使用的最先进的重力流体动力学代码生成了一套孤立的银河系质量星系模拟。在这些模拟中,我们采用了相同的星系盘初始条件和常见的物理模型(例如,辐射冷却和标准化封装的紫外背景)。亚网格物理模型,例如Jeans压力底、恒星形成、超新星反馈能量和金属产生都受到了仔细的限制。在这里,我们发布模拟数据供社区免费使用。在这个版本中,我们包含了Kim et al.(2016)中使用的每个代码在0和5亿年进化时的磁盘快照,来自有和没有恒星形成和反馈的模拟。我们鼓励数值星系形成社区的任何成员利用这些资源进行研究-例如,将他们自己的模拟与AGORA星系进行比较,使用常见的分析yt脚本来获得我们的论文中显示的图,也可以在此版本中获得。

英文摘要:

As part of the AGORA High-resolution Galaxy Simulations Comparison Project (Kim et al. 2014, 2016) we have generated a suite of isolated Milky Way-mass galaxy simulations using 9 state-of-the-art gravito-hydrodynamics codes widely used in the numerical galaxy formation community. In these simulations we adopted identical galactic disk initial conditions, and common physics models (e.g., radiative cooling and ultraviolet background by a standardized package). Subgrid physics models such as Jeans pressure floor, star formation, supernova feedback energy, and metal production were carefully constrained. Here we release the simulation data to be freely used by the community. In this release we include the disk snapshots at 0 and 500Myr of evolution per each code as used in Kim et al. (2016), from simulations with and without star formation and feedback. We encourage any member of the numerical galaxy formation community to make use of these resources for their research - for example, compare their own simulations with the AGORA galaxies, with the common analysis yt scripts used to obtain the plots shown in our papers, also available in this release.
