PHYS3937: Plasma and Astrophysics (Advanced)

Semester 2, 2021 [Normal day] - Camperdown/Darlington, Sydney

: Looking at the sky it is easy to forget our Sun and the stars are continuous giant nuclear explosions, or that nebulas are vast fields of ionized gases, all obeying the same laws of physics as anything else in the universe. Astrophysics gives us great insight in the larger structures of the universe, and plasma physics is key to understanding matter in space, but also in fusion reactors or for advanced material processing. This selective unit in the physics major will provide an introduction to astrophysics and plasma physics, complemented with experimental labs. You will study three key concepts in astrophysics: the physics of radiation processes, stellar evolution, and binary stars. You will gain understanding of the physics of fundamental phenomena in plasmas and apply basic methods of theoretical and experimental plasma physics. The advanced stream goes into more depth in the coursework has more open-ended experimental physics projects: You will learn and apply new experimental and data analysis techniques by designing and carrying out in-depth experimental investigations on selected topics in physics, with expert tutoring. In completing this unit you will gain understanding of the foundations of modern physics and develop skills in experimental physics, measurement, and data analysis.

Assessment summary

  • Assignments: There are three coursework assignments in this unit, one per module, and one larger problem assignment using aspects
    of both modules. Students are encouraged to start early on the problem assignment, as they will be able to solve aspects from it as early as it is released.
  • Plasma physics online quizzes: There will be compulsory online lectures and a small quiz before each lecture starting from week 7; material covered in lectures will assume the reading has been done and will be part lecture, part tutorial. Each lecture's pre-reading quizzes will need to be completed by beginning of the lecture.

  • Astrophysics computer labs: Students only need to attend one lab session. Each lab consists of three checkpoints, all checkpoints must be handed in and marked off by the following lab session.

  • Experimental physics lab books: Every student will carry out two experiments. At least one experiment has to be from the advanced experiment pool.

  • Experimental physics report and peer review: Students will be required to write up one report on one of the experiments completed, based on the material already in their logbook. Reports are to be written in the style of a scientific paper in a specific journal.

  • Final exam: The final exam will have questions covering all coursework aspects of this course (astrophysics and plasma physics), and will be entirely paper-based. This is a closed book exam.

Detailed information for each assessment can be found on Canvas.

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

For more information see sydney.edu.au/students/guide-to-grades.

For more information see guide to grades.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

Academic integrity

The Current Student website  provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.  

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

Learning outcomes are what students know, understand and are able to do on completion of a unit of study. They are aligned with the University's graduate qualities and are assessed as part of the curriculum.

At the completion of this unit, you should be able to:

  • LO1. demonstrate an understanding of key concepts in two areas of physics: astrophysics and plasma physics
  • LO2. apply these concepts to develop models, and to solve qualitative and quantitative problems in scientific contexts, using appropriate mathematical and computing techniques as necessary
  • LO3. design experiments to measure specific effects
  • LO4. compare and critique experimental approaches
  • LO5. communicate scientific information appropriately, through written work
  • LO6. analyse a physical problem in plasma physics and astrophysics develop a formalism appropriate for solving it
  • LO7. demonstrate a sense of responsibility, ethical behaviour, and independence as a learner and as a scientist.

Graduate qualities

The graduate qualities are the qualities and skills that all University of Sydney graduates must demonstrate on successful completion of an award course. As a future Sydney graduate, the set of qualities have been designed to equip you for the contemporary world.

GQ1 Depth of disciplinary expertise

Deep disciplinary expertise is the ability to integrate and rigorously apply knowledge, understanding and skills of a recognised discipline defined by scholarly activity, as well as familiarity with evolving practice of the discipline.

GQ2 Critical thinking and problem solving

Critical thinking and problem solving are the questioning of ideas, evidence and assumptions in order to propose and evaluate hypotheses or alternative arguments before formulating a conclusion or a solution to an identified problem.

GQ3 Oral and written communication

Effective communication, in both oral and written form, is the clear exchange of meaning in a manner that is appropriate to audience and context.

GQ4 Information and digital literacy

Information and digital literacy is the ability to locate, interpret, evaluate, manage, adapt, integrate, create and convey information using appropriate resources, tools and strategies.

GQ5 Inventiveness

Cultural Competence is the ability to actively, ethically, respectfully, and successfully engage across and between cultures. In the Australian context, this includes and celebrates Aboriginal and Torres Strait Islander cultures, knowledge systems, and a mature understanding of contemporary issues.

GQ7 Interdisciplinary effectiveness

Interdisciplinary effectiveness is the integration and synthesis of multiple viewpoints and practices, working effectively across disciplinary boundaries.

GQ8 Integrated professional, ethical, and personal identity

An integrated professional, ethical and personal identity is understanding the interaction between one’s personal and professional selves in an ethical context.
