Self-consistent annihilation simulations of dark matter

暗物质的湮灭信号在很大程度上依赖于暗物质的局部特性及其自我相互作用的方式。使用最新的宇宙学n体模拟将有助于我们理解相互作用和产生的信号。该项目的目的是开发一个自洽的暗物质自湮灭n体模拟，其中暗物质被移除。为了实现自洽自湮灭暗物质的模拟，将创建一个高效的、大规模并行的代码。当相互作用发生时，这个代码将使用概率计算来消除暗物质的质量。该代码将在EAGLE模拟中实现，并对结果进行分析。这个项目的结果将为暗物质的湮灭信号提供一个理论模型。这将允许对湮灭信号施加新的限制，这对切伦科夫望远镜阵列等在宇宙中寻找暗物质的探测实验非常重要。

The annihilation signal of dark matter relies significantly on the local properties of dark matter and how it self-interacts. Using the latest cosmological N-body simulations will help in our understanding of the interactions and the resulting signal. The aim of this project is to develop a self-consistent self-annihilation N-body simulation of dark matter, in which the dark matter is removed. An efficient, massively-parallel code will be created in order to carry out the self-consistent self-annihilating dark matter simulations. This code will use probabilistic calculations to remove dark matter mass on-the-fly, as the interactions take place. The code will be implemented into the EAGLE simulations and the results analysed. The results from this project will provide a theoretical model of the annihilation signal expected from dark matter. This will allow new constraints to be placed on the annihilation signal, which is of great importance to the detection experiments such as the Cherenkov Telescope Array as they search for dark matter in the universe.
