This course is usually offered every odd year (eg 2019)
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.
Upon successful completion, students will have the knowledge and skills to:
- Understand the processes by which continuum and line radiation is produced in the interstellar medium.
- Understand how collisional excitation and photoionization determine the populations of ions in their different energy levels.
- 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.
- Understand the formation of shocks in the interstellar medium and the resultant spectra.
- Understand the physics of the cooling function for astrophysical plasma and its important role in different contexts.
- Understand the physics of dust in the interstellar medium and its effect on the emitted spectrum.
- Participation and performance in lectures and tutorials (10) [LO 1,2,3,4,5,6]
- Assignments (40) [LO 1,2,3,4,5,6]
- Research Project - Essay (25) [LO 1,2,3,4,5,6]
- Resarch Project - Oral presentation (25) [LO 1,2,3,4,5,6]
In response to COVID-19: Please note that Semester 2 Class Summary information (available under the classes tab) is as up to date as possible. Changes to Class Summaries not captured by this publication will be available to enrolled students via Wattle.
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.
The expected workload will consist of approximately 130 hours throughout the semester including:
- Face-to face component which may consist of 4 hours of lectures and tutorials per week
- Approximately 82 hours of self-study which will include preparation for lectures, presentations and other assessment tasks (average 6 hours per week spent on assignments and the major project).
