论文摘要
银河风探测反馈如何调节星系的质量和金属性。银河风具有冷气，主要可观察到吸收和发射线。理论上研究如何产生吸收系需要数值模拟和现实的Starburst紫外线背景。我们使用来自风云相互作用的3D冥王星模拟套件的输出来估算柱密度和温度。然后，为了创建合成光谱，我们开发了一个python界面，通过YT包装基础架构将冥王星模拟与三叉戟链接到三叉戟。首先，我们为Starburst的星形形成率产生紫外线背景。为此，我们使用Starburst99生成的通量，然后通过Cloudy对其进行处理以创建自定义的离子表。随后将这些表读成三叉戟以产生吸收光谱。我们解释了各种软件包和工具如何相互通信，以创建与Starburst系统的光谱能量分布一致的离子光谱。
Galactic winds probe how feedback regulates the mass and metallicity of galaxies. Galactic winds have cold gas, which is mainly observable with absorption and emission lines. Theoretically studying how absorption lines are produced requires numerical simulations and realistic starburst UV backgrounds. We use outputs from a suite of 3D PLUTO simulations of wind-cloud interactions to first estimate column densities and temperatures. Then, to create synthetic spectra, we developed a python interface to link our PLUTO simulations to TRIDENT via the YT-package infrastructure. First we produce UV backgrounds accounting for the star formation rate of starbursts. For this purpose, we use fluxes generated by STARBURST99, which are then processed through CLOUDY to create customised ion tables. Such tables are subsequently read into TRIDENT to generate absorption spectra. We explain how the various packages and tools communicate with each other to create ion spectra consistent with spectral energy distributions of starburst systems.
