Interstellar OH+ , H2O+ and H3O+ along the sight-line to G10.6-0.4

This leads to two pressing questions: (1) whether and how silicates, which are a major constituent of interstellar dust and shown to catalyze H 2 formation at low temperature via

ducing the HI absorption is diffuse, it is expected to produce an absorption signal in [C ii] as well. Note that the figures are negative because they corre- spond to absorption.

In Diderot’s metaphysics of the senses, all the different senses “are just a diversifi ed touch” and sight, the eidetic sense, is the idealist sense: “How deceptive the eye

The plots represent computed absorption profiles corresponding to two different populations for the metastable 6 3Po level, but to the same

Combined Herschel / HIFI and IRAM 30m observations led to the detection of a distant dark cloud (4–5 kpc) along the line of sight of a compact HII region W51. This cloud, named

Methods. At 22.5 ′′ resolution, the CO J=1-0 emission toward NRAO150 is 30-100% brighter at some velocities than seen previously with 1 ′ resolution, and there are some

Spatial dispersion of magnetic fields in molecular clouds from polarisation maps may be used to characterise the power spectrum of magnetised turbulence in the inertial and
