Molecular Gas Morphological Analogs for the Milky Way

The Astrophysical Journal Letters
Complete catalogs of molecular clouds in the Milky Way allow analysis of the molecular medium and the star formation properties of the Milky Way that closely follows the method used for nearby galaxies.

Relative Velocities between 13CO Structures within 12CO Molecular Clouds

The Astronomical Journal
Velocity fields of molecular clouds (MCs) can provide crucial information on the merger and split between clouds, as well as their internal kinematics and maintenance, energy injection and redistribution, and even star formation within clouds.

Detection of Helium Recombination Lines in the Cygnus X Diffuse Ionized Gas: Implications for Galactic Interstellar Medium Studies

The Astronomical Journal
We present the first detection of helium radio recombination lines (HeRRLs) at 800 MHz from the diffuse ionized gas (DIG) in the Cygnus X region, with an ionized helium-to-hydrogen ratio ( ${{n}}_{{\rm{H}}{\rm{e}}}^{+}/{{n}}_{{\rm{H}}}^{+}$ ) of 0.06 ± 0.

Radiative transfer and chemistry in spheroidal interstellar clouds

, 2002
The thesis begins by describing the way in which gas phase chemistry of the interstellar medium can be modelled, and demonstrating the potential significance of chemical reactions on the surfaces of dust grains present in the gas. The dust also serves as

Silicon chemistry in interstellar clouds [PDF]

, 1989
Interstellar SiO was discovered shortly after CO but it has been detected mainly in high density and high temperature regions associated with outflow sources.
