Non-kinematical anisotropies in galaxy clustering and cosmological tests of gravity

我们的项目旨在更新模拟星系内尘埃和分子氢的建模。我们将通过热力学和化学求解器的耦合来实现这一目标，以便更好地模拟尘埃种群增长和被破坏的速率。此外，我们将分子氢添加到化学网络中，使我们能够明确计算其丰度，而不是之前使用的近似方法。这项工作将与SIMBA模拟项目合作完成，我们的新建模程序将作为标准添加到集团内的下一代模拟中。在做这项工作时，我们创建了一个自洽的和物理动机的模型模拟星系的星际介质内的尘埃和分子氢。

Our project aims to update the modelling of dust and molecular hydrogen within simulated galaxies. We will achieve this through the coupling of thermodynamic and chemical solvers in order to better model the rate at which dust populations grow and are destroyed. Furthermore, we add molecular hydrogen into the chemical network which allows us to explicitly calculate its abundance, rather than the approximate methods used before. This work will be done in collaboration with the SIMBA simulation project, and our new modelling procedures will be added to next-generation simulations within the group as standard. In doing this work we create a self-consistent and physically motivated model of dust and molecular hydrogen within the interstellar medium of simulated galaxies.
