title = "Probing the conditions for the atomic-to-molecular transition in the interstellar medium",
abstract = "We examine the physical conditions required for the formation of H2 in the solar neighborhood by comparing Hi emission and absorption spectra toward 58 lines of sight at b<−5◦ to CO(1–0) and dust data. Our analysis of CO-associated cold and warm neutral medium (CNM and WNM) shows that the formation of CO-traced molecular gas is favored in regions with high column densities where the CNM becomes colder and more abundant. In addition, our comparison to the one-dimensional steady-state Hi-to-H2 transition model of Bialy et al. (2016) suggests that only a small fraction of the clumpy CNM participates in the formation of CO-traced molecular gas. Another possible interpretation would be that missing physical and chemical processes in the model could play an important role in H2 formation.",
