Early-Universe Simulations of the Cosmological Axion: Supplementary Data

Public release of the axion field state obtained through simulations of the post-inflationary QCD axion as performed in "Early-Universe Simulations of the Cosmological Axion," from arXiv:1906.00967v1[astro-ph.CO].

This dataset should enable researchers to construct density fields for gravitational simulations for axion structure formation. Alternatively, it provides initial conditions for the further evolution of a realistic axion field configuration to arbitrary late times under classical field dynamics. For detailed instructions regarding the data formatting, units, and density field construction, see README.pdf.

本数据集公开了arXiv:1906.00967v1[astro-ph.CO]收录的《宇宙轴子的早期宇宙模拟》（Early-Universe Simulations of the Cosmological Axion）一文中所开展的暴胀后QCD轴子（QCD axion）模拟得到的轴子（axion）场态。
本数据集可支持研究人员构建用于轴子结构形成的引力模拟密度场；此外，其还可作为初始条件，在经典场动力学框架下，将真实轴子场构型的演化推进至任意晚期时刻。有关数据格式、单位及密度场构建的详细操作说明，请参阅README.pdf。
