This project will be focusing on detailed numerical modelling of the small-scale physics and its effects on the observational features of the Epoch of Reionization. This is geared primarily towards the current LOFAR reionization experiment and in preparation for the near-future SKA one. There is significant parameter space to be explored and a complex reionization physics to be understood for both proper planning of the observations and for reliable interpretation of the obtained data and its connection to the properties of the first galaxies and the progress and duration of the reionization process. As part of this project the student will learn and then further develop a variety of numerical codes and tools, including massively-parallel programming and data analysis. He will also learn the rich physics involved, as well as the basics of radio interferometry and other relevant observational methods.

该项目将侧重于小尺度物理学及其对再电离时代观测特征的影响的详细数值模拟。这主要是为了目前的LOFAR再电离实验和为不久将来的SKA再电离实验做准备。有显着的参数空间进行探索和一个复杂的再电离物理要理解的观测和获得的数据及其连接到第一个星系的属性和再电离过程的进展和持续时间的可靠解释的适当规划。作为该项目的一部分，学生将学习并进一步开发各种数字代码和工具，包括并行编程和数据分析。他还将学习所涉及的丰富物理学，以及无线电干涉测量和其他相关观测方法的基础知识。
