We develop analytical relations, tested against numerical simulations, that connect turbulent velocity scaling to the motions measured in projected emission-line maps. By accounting for the depth of the emitting gas, discrete plasma clumps, and observational resolution, we can use these measurements to constrain the three-dimensional geometry of the gas surrounding galaxies.</p> <p>The paper is now available on arXiv and has been <strong>submitted to AAS Journals</strong>.</p> <p><a href="https://arxiv.org/abs/2609.20929">Read the preprint</a>.</p>
