Origin of the [CII]-deficit
The line of ionized carbon at 158μm, denoted as [CII], is one of the brightest lines originating from star-forming galaxies. Under typical environmental conditions of the interstellar medium (ISM), the…
Expansion of HII-regions
Massive stars emit copious amount of photons that are able to ionize the atom of hydrogen in their nearby environment of the interstellar medium (ISM). This influence of UV radiation…
Fine-structure lines as diagnostic for cloud-cloud collision activity
The dominant process for the galactic star formation is believed to be the collision between giant molecular clouds. The collision triggers the gravitational collapse of the merged clouds, creating star…
