The course coversthe following topics: The diffuse universe; line emission processes; collisional excitation; line transfer effects; collision ionization equilibrium; cooling plasmas; interstellar shocks; theory of photoionised regions; parameters of photoionised regions and interstellar dust.

Students complete two assignments and a major project on the interstellar medium.  The major project is presented as a written report and may be submitted to an astrophysical journal as a publication if the student chooses to prepare their report for a journal after course completion.  The student presents their project to the class as an oral 20 minute (Power point style) presentation.

 

Learning Outcomes

On satisfying the requirements of this course, students will

  1. Understand the processes by which continuum and line radiation is produced in the interstellar medium.
  2. Understand how collisional excitation and photoionization determine the populations of ions in their different energy levels.
  3. Understand the formation of the emission spectrum in photoionised regions including HII regions, planetary nebulae and active galactic nuclei; estimation of the parameters of such regions.
  4. Understand the formation of shocks in the interstellar medium and the resultant spectra.
  5. Understand the physics of the cooling function for astrophysical plasma and its important role in different contexts.
  6. Understand the physics of dust in the interstellar medium and its effect on the emitted spectrum.

Indicative Assessment

2 x assignments each worth 25%. LO 1-6.

Major project: 50% LO 1-6.

The ANU uses Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. While the use of Turnitin is not mandatory, the ANU highly recommends Turnitin is used by both teaching staff and students. For additional information regarding Turnitin please visit the ANU Online website.

Workload

4 hours per week of lectures and tutorials; 6 hours per week spent on assignments and the major project.
