Abstract
In this work we disentangle the underlying physical picture of the in-medium gluon radiation process across its different energy regimes by comparing the recently obtained fully-resummed -- without any further approximations -- BDMPS-Z in-medium emission spectrum with the extensively used analytical approaches. We observe that in the high-energy regime the radiation process is dominated by a single hard scattering, while in the intermediate-energy region coherence effects among multiple scatterings are crucial. Finally, we prove that in the low-energy regime the dynamics is again controlled by a single scattering but where one must include a suppression factor accounting for the probability of not having any further scatterings.

Strengths
The presentation is clear and well-written, and comprehensible to a non-expert. Comparisons and highlighting of agreement and differences with respect to pre-existing approximations are very clear.
Weaknesses
The general context of the work and the inputs to the calculations are not clear to a non-expert, but this is not a major problem for the intended purpose, and the relevant introductory material is cited.
Report
A well-presented and clear report on an interesting development, with good comparison to previous methods.
