项目摘要

New accurate atomic data are urgently needed for wide applications in modern astrophysics, particularly large scale Galactic spectroscopic surveys where hundreds of thousands of astrophysical spectra, recorded with state of the art astronomical spectrographs, are being analysed. This PhD project will include high resolution spectroscopic (using the technique of Fourier Transform Spectroscopy) studies of astrophysically important elements, for direct application to astronomy. The student will learn state of the art spectroscopy techniques at our laboratory in Imperial College London, where the visible to vacuum ultraviolet spectra can be observed. We also anticipate the student will also spend time with our collaborators at NIST (Washington USA) to work on observing infra red spectra. This experimental work will be combined with detailed analysis to yield the new atomic data that will be used by astronomers, for example atomic energy levels and wavelengths, transition probabilities, all needed to interpret astrophysical spectra meaningfully. We also expect this studentship to include an element of the student undertaking atomic structure calculations of the atomic species being studied, through collaboration with theoretical groups. We have strong links with the astronomical community that guarantees immediate dissemination of the new data, and we anticipate our student will visit some of these astronomers to work on the application of their new data.

现代天体物理学的广泛应用迫切需要新的精确原子数据，特别是大规模的银河光谱调查，其中正在分析用最先进的天文光谱仪记录的数十万个天体物理光谱。这个博士项目将包括天体物理学重要元素的高分辨率光谱（使用傅里叶变换光谱技术）研究，直接应用于天文学。学生将在伦敦帝国理工学院的实验室学习最先进的光谱技术，在那里可以观察到可见光到真空紫外光谱。我们还预计学生也将花时间与我们的合作者在NIST（华盛顿美国）的工作观察红外光谱。这项实验工作将与详细的分析相结合，产生天文学家将使用的新原子数据，例如原子能级和波长，跃迁概率，所有这些都需要有意义地解释天体物理光谱。我们还希望这个奖学金包括学生的一个元素，通过与理论团体的合作，进行正在研究的原子种类的原子结构计算。我们与天文学界有着密切的联系，这保证了新数据的立即传播，我们预计我们的学生将访问其中一些天文学家，以研究他们的新数据的应用。
