论文摘要

我们介绍了一个工具,该工具求解了方程式的Schrödinger-euler-Poisson系统,并允许研究超轻玻色粒暗物质之间的相互作用,其动力学用Schrödinger-Poisson系统和发光物质描述,作为第一个组件可压缩的理想理想的理想理想的理想的理想的理想的理想的理想的理想的理想流体。两个物质字段通过泊松方程耦合,其来源是添加暗物质和流体密度。我们描述了用于求解方程系统的数值方法,并为两个组件中的每个组件中的每一个都进行了测试,这些方法显示了代码的准确性和收敛属性。作为简单可能的应用,我们提供了一些玩具场景:i)暗物质与气体云之间的合并,ii)玻色粒暗物质和流体配置的合并,以及ii)合并后的合并特性,包括气体与气体的相关性以及振荡核心和气体的振荡之间的相关性。

We introduce a tool that solves the Schrödinger-Euler-Poisson system of equations and allows the study of the interaction between ultralight bosonic dark matter, whose dynamics is described with the Schrödinger-Poisson system and luminous matter which, as a first approximation, is modeled with a single component compressible ideal fluid. The two matter fields are coupled through the Poisson equation, whose source is the addition of both, dark matter and fluid densities. We describe the numerical methods used to solve the system of equations and present tests for each of the two components, that show the accuracy and convergence properties of the code. As simple possible applications we present some toy scenarios: i) the merger between a core of dark matter with a cloud of gas, ii) the merger of bosonic dark matter plus fluid configurations, and iii) the post merger properties, including the dark-matter offset from gas and the correlation between oscillations of the bosonic core and those of the gas.
