ABSTRACT Context. Measurement of the Galactic neutral atomic hydrogen (H i) column
density, NH i, and brightness temperatures, TB, is of high scientific value for a broad range of …

Probability distribution functions of the total hydrogen column density (N-PDFs) are a
valuable tool for distinguishing between the various processes (turbulence, gravity, radiative …

We analyse column density and temperature maps derived from Herschel dust continuum
observations of a sample of prominent, massive infrared dark clouds (IRDCs) ie G11. 11 …

Context. Carbon monoxide (CO) is a poor tracer of H 2 in the diffuse interstellar medium
(ISM), where most of the carbon is not incorporated into CO molecules, unlike the situation at …

Recent Planck results have shown that radiation from the cosmic microwave background
passes through foregrounds in which aligned dust grains produce polarized dust emission …

Characterizing the structure of the Galactic interstellar medium (ISM) in three dimensions is
of high importance for accurate modeling of dust emission as a foreground to the cosmic …

Context. The H i 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 …

High-latitude intermediate-velocity clouds (IVCs) are part of the Milky Way's HI halo and
originate from either a galactic fountain process or extragalactic gas infall. They are partly …

We have used the Green Bank Telescope to search for the OH molecule at several locations
in the Smith Cloud, one of the most prominent of the high-velocity clouds surrounding the …
