Probing the Ionization Rate of Molecular Hydrogen Near the Galactic Center

In this article, the authors measure the cosmic ray ionization rate within a few parsecs of the galactic center. They find that the cosmic ray ionization rate is an order of magnitude larger than the galactic standard and also that the molecular gas near the galactic center is much warmer than the typical galactic molecular cloud.

Astrophysical Classics: Larson’s “Laws”

This paper presents three famous relations very important for understanding the inner workings of molecular clouds and star formation processes.

Do we really need a ring?

Understanding the structure of our Milky Way is as difficult as trying to see the forest from the trees. Among the many uncertainties, we don’t know whether the molecular ring is really due to a ring structure or it is simply produced by the spiral arms.
