Molecular Tracers Of Star Formation Feedback In Nearby Galaxies, Mark Gorski
Molecular Tracers Of Star Formation Feedback In Nearby Galaxies, Mark Gorski
Physics & Astronomy ETDs
The energy and momentum injected into the ISM from stars has a drastic effect on the star formation history of a galaxy. This is called feedback. It is responsible for the inefficient collapse of the ISM into stars. The ``Survey of Water and Ammonia in Nearby Galaxies" (SWAN) is a survey of molecular line tracers in four nearby galaxies. By using molecular tracers of feedback, we provide insights into the star forming ecosystem of the galaxies NGC 253, IC 342, NGC 6946, and NGC 2146. These galaxies were chosen to span an order of magnitude in star formation rate and …
