The high-velocity cloud complex Galactic center negative as seen by EBHIS and GASS. I. Cloud catalog and global properties

Using higher angular resolution than previously available, this study shows how a complex of high-velocity clouds resolves into structures on column density scales that are an order of magnitude lower than previously found. In addition, the authors compare several lines of sight with low-velocity, metallic absorption systems against QSOs and identify individual components. The survival of these structures in the hot Galactic halo is also addressed.
