Pre-requisites: MATH6202 (Physicists and Astronomers); MATH2303 (Mathematicians) Structure: 3 hour lectures per week
This course is available to 3rd or 4th year students with a good mathematical ability.
The course introduces Einstein’s theories of special and general relativity. Special relativity shows how measurements of physical quantities such as time and space can depend on an observer’s frame of reference. Relativity also emphasises that there exists an underlying physical description independent of observers. This physical description uses mathematical objects called tensors. Tensor notation simplifies the form of the Maxwell equations and reveals their power and beauty. The Maxwell equations provide a description of electromagnetism compatible with special relativity. However, no similar equations exist for gravitation. Instead, a more general form of relativity is needed where space-time has curvature. Curvature, in effect, replaces the gravitational field. Objects no longer accelerate due to gravitational forces; instead they move along geodesics whose shape is determined by the curvature. Furthermore, rather than mass being the source of the gravitational field, a massive object warps the space around it, generating curvature.
MATH 3306 COSMOLOGY
Pre-requisites: MATH3305 – Mathematics for General Relativity Structure: 3 hour lectures per week This course is available to 3rd or 4th year students with a good mathematical ability.
Cosmology is the study of the history and structure of the Universe. Cosmologists usually assume that the Universe is highly symmetric on large scales; under this assumption the equations of general relativity reduce to two simple ordinary differential equations. These equations govern the expansion of the Universe. These equations are studied in detail, and show how observations are affected by the expansion and curvature of the Universe. The course then covers the astronomical methods used to determine the expansion rate (i.e. the Hubble constant) and the mass density of the Universe. Physical processes in the early universe such as nucleo-synthesis, the formation of the microwave background, and galaxy formation will also be studied. The course begins with a description of black holes and ends with speculative topics including inflation and cosmic strings.

ASTM109 Stellar Structure and Evolution ·
Course outline:
Stars are important constituents of the universe. This course starts from well known physical phenomena such as gravity, mass conservation, pressure balance, radiative transfer of energy and energy generation from the conversion of hydrogen to helium. From these, it deduces stellar properties that can be observed (that is, luminosity and effective temperature or their equivalents such as magnitude and colour) and compares the theoretical with the actual. In general good agreement is obtained but with a few discrepancies so that for a few classes of stars, other physical effects such as convection, gravitational energy generation and degeneracy pressure have to be included. This allows an understanding of pre-main sequence and dwarf stages of evolution of stars, as well as the helium flash and supernova stages.
Syllabus:
The material presented in this module consists of the following: ·
Observational properties of stars, the H-R diagram, the main sequence, giants and white dwarfs. ·
Properties of stellar interiors: radiative transfer, equation of state, nuclear reactions, convection. ·

ASTM024 M.Sc. Astrophysics Project
The research project is a major component of the Astrophysics MSc in the final year. It is a fantastic opportunity to acquire valuable research skills and carry out high level astrophysical work, supervised by a member of academic staff.
The project gives students scope to work independently and critically on the topic of interest to them. It may be a theoretical topic, or it may involve computational work, or analysis of observational work by others. In all cases the emphasis should be on the astrophysics within the field chosen. The relevance of the work in the wider context of the subject should be explained as part of the introductory section. The project will normally require the study of original papers, show evidence of critical assessment and include a substantial component of independent work. It is not expected to include original research by the student, but it will be regarded favourably if it does. The report should be around 15,000 words. In assessing the project, the examiners will pay particular attention to clarity of presentation, evidence that the student has worked critically and independently, and the adequacy of references to original papers. Students must choose a topic and find a supervisor by the beginning of January.
The award of an MSc is based on the end-of-year examinations and the project. The project is an important component of the MSc, corresponding to 4 modules, and you should devote substantial effort to it during the year. The examinations and the project must both be passed for the award of the MSc. Distinction can only be attained in the MSc if the project is at the required level.
