PHY1021 : Introductory Astrophysics

Semester 1 Credit Value: 10
ECTS Credits: 5.0


To understand how we measure properties of astrophysical bodies and to understand the application of basic physical laws to those bodies.

Description: Since the beginning of human inquiry we have wondered what our place in the Universe is and if we're alone. In order to answer these questions the branch of Astrophysics involves observing astronomical bodies and applying physical laws in order to understand them. This requires cutting edge observations across the electromagnetic spectrum as well as application of physics ranging from particle physics to general relativity. This module will introduce a basic understanding of how we observe astrophysical bodies and how we apply physical laws to those bodies in order to ultimately understand the Universe.

Teaching Rationale And Relationship

Lectures are used for the delivery of theory and explanation of methods, illustrated with examples, and for giving general feedback on marked work. Problem Classes are used to help develop the students’ abilities at applying the theory to solving problems. Drop-in's are used to identify and resolve specific queries raised by students and to allow students to receive individual feedback on marked work.

Assessment Methods

The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship

A formal unseen examination is appropriate for the assessment of most material in this module. Two written assignments are used to develop students' problem solving techniques, to practise the methods learnt in the module, to receive feedback for formative assessment and to prepare students for the class tests. Two class tests (each worth 20% in total) provide formative as well as summative assessment. Peer instruction assessment will test students’ communication skills.
