Compact Galactic Neutral Hydrogen Clouds in the GALFA-HI Survey
… five populations of compact neutral hydrogen clouds. We began by developing a machine-vision algorithm to identify compact clouds in the GALFA-HI Data Release 1. Based on position, velocity, and linewidth we separated the 1964 identified clouds into five populations: galaxy candidates, …

Dynamische Stabilisierung von Hochgeschwindigkeitswolken im galaktischen Halo
HI observations of high-velocity clouds (HVCs) indicate that they are interacting with their ambient medium. In this thesis, the question on the dynamical and thermal stabilization of a cold dense neutral cloud in a hot, thin, and magnetized ambient halo plasma is addressed. The results of …

A study of the absorption characteristics of gaseous galaxy halos in the local Universe
… evolution. For the Milky Way, the so-called high-velocity clouds (HVCs), fast moving neutral gas complexes in the halo that can be traced by absorption-line measurements, are believed to play a crucial role in the overall matter cycle in our Galaxy. Over the last decades, the properties of …
