论文摘要
作为Agora高分辨率银河模拟比较项目的一部分(Kim等人,2014,2016),我们使用9个最先进的Gravito-Hydrodynamics代码生成了一套孤立的银河系质量星系模拟,广泛用于数值星系形成社区。在这些模拟中,我们采用了相同的银河磁盘初始条件以及常见的物理模型(例如,通过标准化包装套件,辐射冷却和紫外线背景)。仔细限制了牛仔裤压力层,恒星形成,超新星反馈能量和金属产生等亚网格物理模型。在这里,我们发布了将由社区自由使用的仿真数据。在此版本中,我们按照Kim等人使用的每个代码在0和500myr的进化中包括磁盘快照。 (2016年),来自有和没有星形形成和反馈的模拟。我们鼓励任何数字银河形成社区的任何成员将这些资源用于研究 - 例如,将自己的模拟与Agora Galaxies进行比较,以及用于获取论文中显示的情节的常见分析YT脚本,也可以在本版本中获得。
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.
