The galactic fountain of high-velocity clouds
Abstract
The paper examines whether high-velocity clouds of neutral hydrogen can condense from a hot dynamic corona above the plane of the Galaxy. A model is developed for the trajectories of clouds which matches all observational velocity features of the HVC. Further, the position for the formation of clouds is deduced, and the dynamics of a hot corona of cosmic abundance are investigated, as well as the condensation of clouds within it. Finally, the hydrodynamics of coronal gas are combined with the appearance of HVC on the sky.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
