Aims

To enable students to gain an understanding of the standard cosmological model (describing the constituents, history, and large-scale physical laws of the Universe), as well as how astronomical observations inform our understanding of this model.

Outline Of Syllabus

Describing an expanding Universe:
The Friedmann, acceleration & fluid equations,
Spatial curvature,
Radiation and matter in the Universe,
The cosmological constant,
Distances in an expanding Universe.

The early Universe:
Cosmic microwave background radiation,
Big-bang nucleosynthesis,
Inflation.

Our standard cosmological model and modern observational cosmology:
The LCDM (Lambda – Cold Dark Matter) Model,
Cosmic microwave background anisotropies,
The matter power spectrum.

Intended Knowledge Outcomes

At the end of the module a student will be able to:

•       Discuss the physical significance of solutions to the equations which govern an expanding Universe (the Friedmann, acceleration, and fluid equations)
•       Recall and describe (qualitatively and mathematically) the key processes of the early Universe (inflation, big-bang nucleosynthesis, the origin of cosmic microwave background radiation)
•       Discuss the physical meaning of the parameters of the standard cosmological model of Lambda-CDM

Intended Skill Outcomes

At the end of the module a student will be able to:

•       Solve the equations which govern an expanding Universe (the Friedmann, acceleration, and fluid equations) for a given cosmological scenario
•       Demonstrate how a given variation in the values of relevant physical parameters or model choices would impact the key processes of the early Universe (inflation, big-bang nucleosynthesis, the origin of cosmic microwave background radiation)
•       Demonstrate how a given variation in the values of the parameters of the standard cosmological model (Lambda-CDM) would impact upon key statistics of modern cosmology (CMB anisotropies, the power spectrum of matter)

Students will develop skills across the cognitive domain (Bloom's taxonomy, 2001 revised edition): remember, understand, apply, analyse, evaluate and create.

Teaching Rationale And Relationship

The teaching methods are appropriate to allow students to develop a wide range of skills, from understanding basic concepts and facts to higher-order thinking. Lectures are used for the delivery of theory and explanation of methods, illustrated with examples, and for giving general feedback on marked work. Lectures will include integrated interactive teaching methods and worked examples of problems such as would normally occur in a problems class.

Assessment Rationale And Relationship

A substantial formal unseen and closed-book examination is appropriate for the assessment of the learning outcomes in this module. The format of the examination will enable students to reliably demonstrate their own knowledge, understanding and application of learning outcomes. The assurance of academic integrity forms a necessary part of programme accreditation.

Examination problems may require a synthesis of concepts and strategies from different sections, while they may have more than one ways for solution. The examination time allows the students to test different strategies, work out examples and gather evidence for deciding on an effective strategy, while carefully articulating their ideas and explicitly citing the theory they are using.

A coursework assessment is also included for the purpose of supporting learning, providing skills practice, and promoting assessment literacy. In keeping with the University Framework for Assessment Design, this coursework is a lower-stakes summative assessment rather than a formative assessment, in recognition that this is likely to be more beneficial than a formative assessment in encouraging broad student engagement.
