The low-metallicity ISM: From high redshift to the local Universe

这里提出的项目是“低金属丰度ISM：金属富集、化学、反馈和磁场”项目的延续。在之前的项目中，我们在ISM中研究了超新星爆炸与磁场结构的相互作用，开发了用于数值模拟化学建模的KROME软件包，并在低金属丰度ISM中进行了一些首次应用。在第二个资助期，我们计划在附近矮星系的背景下研究化学和湍流磁场放大的含义，因为来自赫歇尔和先进无线电设施（如LOFAR）的新数据为他们的ISM结构提供了新的见解。具体来说，我们的目标是在低金属丰度下建立ISM相位的详细模型（子项目ISMPHASES），我们将探索超新星反馈存在下湍流磁场放大的结果（子项目EXPLOSION）。例如，这些计划使我们能够探测远红外-射电相关性是否在矮星系中也适用，并有助于解释赫歇尔线数据。

The project proposed here is a continuation of the project "The low-metallicity ISM: Metal enrichment, chemistry, feedback and magnetic fields". In the previous project, we have investigated the interplay of supernova explosions with magnetic field structures in the ISM, developed the KROME package for the modelling of chemistry in numerical simulations and pursued some first applications in the low-metallicity ISM. In the second funding period, we plan to investigate the implications of chemistry and turbulent magnetic field amplification in the context of nearby dwarf galaxies, as new data from Herschel and advanced radio facilities like LOFAR provide new insights into the structure of their ISM. Specifically, we aim for a detailed modelling of the ISM phases at low metallicity (sub-project ISMPHASES), and we will explore the result of turbulent magnetic field amplification in the presence of supernova feedback (sub-project EXPLOSION). These projects allow us, for instance, to probe whether the far-infrared - radio correlation should hold even in dwarf galaxies, and help with the interpretation of Herschel line data.
