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…
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…
A survey of HI gas toward the Andromeda Galaxy
J. Kerp, P. M. W. Kalberla, N. Ben Bekhti +3
The subsequent coalescence of low--mass halos over cosmic time is thought to be the major formation channel of massive spiral galaxies like the Milky Way and the Andromeda Galaxy (…
Star formation in a diffuse high-altitude cloud?
J. Kerp, D. Lenz, T. Roehser
A recent discovery of two stellar clusters associated with the diffuse high-latitude cloud HRK 81.4-77.8 has important implications for star formation in the Galactic halo. We deri…
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…
