Probing the intergalactic and circumgalactic medium in absorption and emission.

在这个项目中，我们将结合新的流体动力学模拟和先进的辐射传输技术，开发新的银河系和环星系介质的发射和吸收特性模型。该项目将侧重于将小尺度的环星系介质的特性与大尺度的星系间介质的特性联系起来，正如吸收和发射光谱学所探测的那样。通过生成发射线和吸收线的模拟观测值，这项研究将为正在进行的和未来的调查(如VLT的DESI和MUSE计划)提供最先进的预测和建模，这些计划正在提供并将提供一个前所未有的关于星系间/绕星系介质作为红移函数的性质的看法。

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.
