The PhD project will focus on performing radiative transfer simulations to compute synthetic spectra and light curves from explosion models and comparing these to real observational data.The student will learn the physical principles and computational algorithms used in Monte Carlo radiative transfer calculations and will become experienced in running and analysing the results of simulations. The project will focus on a combination of improving the quality of the simulations (improving and testing of microphysics) and modelling of observations. This work be carried out in the context of international collaborations with theorists (particularly those specialising in thermonuclear supernova explosions) and supernova observers (at Queens University Belfast, and internationally).

博士项目将侧重于进行辐射传输模拟计算合成光谱和光变曲线从爆炸模型和比较这些真实的观测数据。学生将学习的物理原理和计算算法用于蒙特卡罗辐射传输计算，并将成为运行和分析模拟结果的经验。该项目将侧重于提高模拟质量（改进和测试微观物理学）和观测建模的结合。这项工作将在与理论家（特别是那些专门研究热核超新星爆炸的理论家）和超新星观测者（在贝尔法斯特皇后大学和国际上）进行国际合作的背景下进行。
