Outline

Overview

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

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.

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 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.

Use of generative artificial intelligence (AI) and automated writing tools

You may only use generative AI and automated writing tools in assessment tasks if you are permitted to by your unit coordinator. If you do use these tools, you must acknowledge this in your work, either in a footnote or an acknowledgement section. The assessment instructions or unit outline will give guidance of the types of tools that are permitted and how the tools should be used.

Your final submitted work must be your own, original work. You must acknowledge any use of generative AI tools that have been used in the assessment, and any material that forms part of your submission must be appropriately referenced. For guidance on how to acknowledge the use of AI, please refer to the AI in Education Canvas site.

The unapproved use of these tools or unacknowledged use will be considered a breach of the Academic Integrity Policy and penalties may apply.

Studiosity is permitted unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission as detailed on the Learning Hub’s Canvas page.

Outside assessment tasks, generative AI tools may be used to support your learning. The AI in Education Canvas site contains a number of productive ways that students are using AI to improve their learning.

Learning support

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.
