PHYS3037: Plasma and Astrophysics

Semester 1, 2026 [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. Examples will be given, where appropriate, of the application of these concepts to naturally occurring and man-made plasmas. You will learn and apply new experimental and data analysis techniques by 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. You are encouraged to start early on the problem assignment, as you 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 and/or quizzes will need to be completed by the beginning of the lecture.
  • Astrophysics computer labs: There are four computer labs; these can be completed on your own, or you may attend the help session on Thursdays in weeks 2-5.
  • Experimental physics logbooks: Every student will carry out one or two experiments (the total number of experiments will be advised by the laboratory coordinator at the beginning of the semester).  Experiments are to be completed in the times allocated to you. You must record the experiments you perform in a logbook (In Class experiment recording on logbook) as each experiment is carried out. This is the written record of the experiment. You should carefully read the section “Guidelines for Recording Experimental Work,” in the Experimental Physics Handbook (on Canvas), to see what is expected to be included in a logbook. Tutors will be available to help you. This is a hurdle assessment. Must be attempted & must meet hurdle mark threshold otherwise = AF grade
  • Experimental physics report: You will be required to write up one report on one of the experiments you do, based on the material already in your logbook. Reports are to be written in the style of a scientific paper in a specific journal. It is essential that you refer to the separate document “Senior Experimental Physics Report Guidelines” for instructions (available on Canvas). The experimental physics report is compulsory, and not handing in a report will lead to an Absent Fail grade for the whole unit. It is a hurdle assessment.
  • Experimental skills workshop and quizzes: You will also attend Experimental Skills Workshop in Weeks 1 and 10, and there will be quizzes on experimental skills available on Canvas.
  • 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. Must be attempted & must meet hurdle mark threshold; otherwise = AF grade
     
    Detailed information for each assessment can be found on Canvas.

Final exam: If a second replacement exam is required, this exam may be delivered via an alternative assessment method, such as a viva voce (oral exam). The alternative assessment will meet the same learning outcomes as the original exam. The format of the alternative assessment will be determined by the unit coordinator.

The final exam is compulsory. Failure to submit will result in an absent fail grade (AF) for the unit.

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.

Use of generative artificial intelligence (AI)

You can use generative AI tools for open assessments. Restrictions on AI use apply to secure, supervised assessments used to confirm if students have met specific learning outcomes.

Refer to the assessment table above to see if AI is allowed, for assessments in this unit and check Canvas for full instructions on assessment tasks and AI use.

If you use AI, you must always acknowledge it. Misusing AI may lead to a breach of the Academic Integrity Policy.

Visit the Current Students website for more information on AI in assessments, including details on how to acknowledge its use.

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 University expects students to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.

Our website provides information on academic integrity and the resources available to all students. This includes advice on how to avoid common breaches of academic integrity. Ensure that you have completed the Academic Honesty Education Module (AHEM) which is mandatory for all commencing coursework students

Penalties for serious breaches can significantly impact your studies and your career after graduation. It is important that you speak with your unit coordinator if you need help with completing assessments.

Visit the Current Students website for more information on AI in assessments, including details on how to acknowledge its use.

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.

Support for students

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. carry out and analyse 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, and develop a formalism appropriate for solving it
  • LO7. demonstrate a sense of responsibility, ethical behaviour, and independence as a learner and as a scientist.
