Observations of magnetic fields in the Milky Way and in nearby galaxies with a Square Kilometre Array
R. Beck, B. M. Gaensler
The role of magnetic fields in the dynamical evolution of galaxies and of the interstellar medium (ISM) is not well understood, mainly because such fields are difficult to directly…

Hyperfine Structure in H^{13}CO^{+} and ^{13}CO: measurement, analysis, and consequences for the study of dark clouds
Johannes Schmid-Burgk, Dirk Muders, Holger S. P. Mueller +1
The magnetic moment of the ^{13}C nucleus is shown to provide a potentially useful tool for analysing quiescent cold molecular clouds. We report discovery of hyperfine structure in…
