Semester 2

Prerequisites / Co-requisites

The module will assume prior knowledge equivalent to the following modules. If you have not taken these modules you should consult the module descriptors. PHY3038 Special Relativity; PHY2071 Introduction to Astronomy. Basic programming skills in either Fortran, C, C++ or Python are also required.

Module content

General relativity lectures:

• Introduction (inadequacy of Newtonian description, Special Relativity and

Minkowski metric, Einstein’s principles of equivalence)

• Mathematics of General Relativity (Forms, vectors and tensors, covariant

derivatives and connections, parallel transport and geodesics, curvature)

• Principles of General Relativity (Einstein’s field equations, the Schwarzschild

solution, testing of General Relativity, black holes)

• Gravitational radiation

General relativity computer lab:

• The two-body problem in classical mechanics

• Implementation of an N-body integrator to study the two-body problem

• The Post-Newtonian approximation

• Implementation of Post Newtonian corrections in the N-body integrator

• Application of the N-body integrator to the study of 3 astrophysical problems:

Mercury’s precession of the perihelion, the orbits of the S-stars in the centre of the

Milky Way, energy losses in black hole binaries due to emission of gravitational

radiation

Assessment pattern

Assessment type | Unit of assessment | Weighting |
---|---|---|

Examination | END OF SEMESTER EXAMINATION | 70 |

Coursework | COMPUTATIONAL COURSEWORK | 30 |

Alternative Assessment

None.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate understanding of the formalism of general relativity, aspects of differential geometry relevant to gravitating systems and applications underpinning experimental tests of general relativity.

Thus, the summative assessment for this module consists of:

• One final exam of 1.5 hours with 2 questions to be chosen out of 3.

• One report to be submitted by the end of the course, including a listing of the computer code and a critical discussion of the results obtained for the 3 astrophysical problems.

Formative assessment and feedback

During lectures students will have group problems to apply theory covered with direct

interaction with the lecturer and feedback on their understanding.

The students will be assisted in the development of the computer code and will receive verbal feedback during the lab sessions.

Module aims

- This module aims to:

• Give the students a clear understanding of the limits of Newtonian mechanics and

Special Relativity

• Introduce the principles and formalism of General Relativity

• Show how to apply the Post Newtonian approximation to astrophysical systems

Learning outcomes

006 | Ability to judge the short-comings in the Newtonian theory of gravity, the problem of defining inertial frames, and the reasons why Special Relativity fails to resolve these issues | KCT |

Overall student workload

Lecture Hours: 22

Laboratory Hours: 11

Methods of Teaching / Learning

The learning and teaching strategy is designed to enable students to understand the fundamental concepts involved in General

Relativity.

The learning and teaching methods include:

• Lectures: 2 hours lecture per week x 11 weeks

• Computer Lab: 1 hour per week x 11 weeks

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
