Probing the intergalactic and circumgalactic medium in absorption and emission.

在这个项目中，我们将开发星系际和环星系介质的发射和吸收特性的新模型，结合新的流体动力学模拟与先进的辐射传输技术。该项目将侧重于将小尺度的环星系介质的性质与较大尺度的星系间介质的性质联系起来，如吸收和发射光谱学所探测的那样。通过生成模拟观测的发射和吸收线，这项研究将提供最先进的预测和建模，为正在进行和未来的调查（如DESI和VLT的MUSE计划），这是提供并将提供一个前所未有的观点的性质的星系际/环星系介质作为红移的函数。

In this project, we will develop new models of the emission and absorption properties of the intergalactic and circumgalactic medium combining novel hydrodynamic simulations with advanced radiative transfer techniques. The project will focus on connecting the properties of the circumgalactic medium on small scales with the properties of the intergalactic medium at larger scales, as probed by spectroscopy both in absorption and emission. By generating mock observables for emission and absorption lines, this study will provide state-of-the art predictions and modeling for ongoing and future surveys (such as DESI and MUSE programmes at VLT), which are providing and will provide an unprecedented view of the nature of the intergalactic/circumgalactic medium as a function of redshift.
