Laboratory Astrophysics: Spectroscopy of astrophysically important elements and applications of the new atomic data to astrophysics.

现代天体物理学的广泛应用迫切需要新的准确的原子数据，特别是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的大规模银河系光谱调查。这个博士项目将包括对天体物理上重要元素的高分辨率光谱研究(使用傅里叶变换光谱技术)，以直接应用于天文学。这名学生将在我们位于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的紫外线光谱。我们还预计，这名学生还将与我们在NIST(美国华盛顿)的合作者一起观察红外光谱。这项实验工作将与详细的分析相结合，以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，所有这些都是有意义地解释天体物理光谱所需的。我们还希望这个学生资格包括通过与理论小组合作，对正在研究的原子物种进行原子结构计算的学生的一部分。我们与天文学社区有着密切的联系，这保证了新数据的立即传播，我们预计我们的学生将拜访其中一些天文学家，研究他们的新数据的应用。

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.
