All-sky census of Galactic high-latitude molecular intermediate-velocity clouds
T. Röhser, J. Kerp, D. Lenz +1
The HI halo clouds of the Milky Way, and in particular the intermediate-velocity clouds (IVCs), are thought to be connected to Galactic fountain processes. Observations of fountain…
HI4PI: A full-sky HI survey based on EBHIS and GASS
HI4PI Collaboration, N. Ben Bekhti, L. Flöer +18
Measurement of the Galactic neutral atomic hydrogen (HI) column density, NHI, and brightness temperatures, Tb, is of high scientific value for a broad range of astrophysical discip…
High-resolution HI and CO observations of high-latitude intermediate-velocity clouds
T. Röhser, J. Kerp, N. Ben Bekhti +1
Intermediate-velocity clouds (IVCs) are HI halo clouds that are likely related to a Galactic fountain process. In-falling IVCs are candidates for the re-accretion of matter onto th…
Cygrid: A fast Cython-powered convolution-based gridding module for Python
B. Winkel, D. Lenz, L. Flöer
Data gridding is a common task in astronomy and many other science disciplines. It refers to the resampling of irregularly sampled data to a regular grid. We present cygrid, a libr…
Cold Milky Way Hi gas in filaments
P. M. W. Kalberla, J. Kerp, U. Haud +4
We investigate data from the Galactic Effelsberg--Bonn HI Survey (EBHIS), supplemented with data from the third release of the Galactic All Sky Survey (GASS III) observed at Parkes…
Far-infrared study of tracers of oxygen chemistry in diffuse clouds
H. Wiesemeyer, R. Güsten, S. Heyminck +8
Context. The chemistry of the diffuse interstellar medium rests upon three pillars: exothermic ion-neutral reactions (" cold chemistry "), endothermic neutral-neutral reactions wit…
