模拟从毫米到紫外线的发射线并产生合成光谱对于很好地理解观测结果至关重要，但这是一门充满危险的艺术。这是2018年举行的为期3天的会议“Walking the Line”的会议记录，该会议汇集了从事发射线模拟不同方面工作的科学家，以分享知识并讨论方法。讨论了从毫米到紫外光谱的发射线，大部分集中在星际介质上，但也有一些关于环星系介质的主题。一个有用的模型最重要的品质是与观察和实验的良好协同作用。确定了模拟线发射的挑战，其中一些挑战已经在研究中，而另一些挑战必须在未来解决，以便模型与观测结果一致。本文概述了在若干领域内为实现这种协同作用而取得的最新进展，从微观物理到银河和环银河尺度。
Modeling emission lines from the millimeter to the UV and producing synthetic spectra is crucial for a good understanding of observations, yet it is an art filled with hazards. This is the proceedings of “Walking the Line”, a 3-day conference held in 2018 that brought together scientists working on different aspects of emission line simulations, in order to share knowledge and discuss the methodology. Emission lines across the spectrum from the millimeter to the UV were discussed, with most of the focus on the interstellar medium, but also some topics on the circumgalactic medium. The most important quality of a useful model is a good synergy with observations and experiments. Challenges in simulating line emission are identified, some of which are already being worked upon, and others that must be addressed in the future for models to agree with observations. Recent advances in several areas aiming at achieving that synergy are summarized here, from micro-physical to galactic and circum-galactic scale.
