DEPARTMENT

DESCRIPTION 
Cosmology endeavours to use the scientific method to understand the origin, evolution and ultimate fate of the Universe as a whole.
This studyunit will lay the foundations for advanced study and research in Astrophysics in general and theoretical physics in particular. There will be an introduction to the modern mathematical framework of General Relativity which is the cornerstone of current research in all of cosmology. This will be followed by an introduction into the foundations of the modern cosmology.
This is not a basic studyunit in physics but is specifically designed to allow for the easy access of Standard Cosmology in a clear and presentable manner. It is strongly recommended that the student also take MAT3513 'Tensors and Relativity' (5 Credits), but this is not necessary, the course will be selfcontained.
A more detailed breakdown of the studyunit is given below:
 Special Relativity: Tensor Formalism and Notation, Introduce the Concept of a Metric, the Nature of Physical Laws in Tensor Forms;  Equivalence Principles: The Weak and Strong Equivalence Principles and their Applications in Gravitational Experiments;  Introduce General Relativity: Introduce to Curved Spacetime, The Schwarzschild Solution, Classical Tests of General Relativity;  Cosmology: The FriedmannLemaîtreRobertsonWalker metric, Concept of the Big Bang, The Hubble Parameter and The Constituents that make up the Universe, The Deceleration Parameter, Basic Calculations on the CMB Pattern, Inflation.
StudyUnit Aims:
The studyunit aims to give students a general background in the field of cosmology through the prism of general relativity. This will involve starting from the bedrock of special relativity which will lead to general relativity. By investigating Einstein’s theory and its solutions the studyunit aims to then expand on the modern description of the Universe with a look at some of the main epoch of its history. The studyunit will close with a description of some of the contemporary topics modern cosmology investigates.
Learning Outcomes:
By the end of this studyunit, the student will be able to:
 Describe the general features of Einstein’s theory of general relativity;  Predict some of general relativity’s standard tests;  Describe in its mathematical detail some of the basic elements of modern cosmology;  Explain some long standing problems in modern cosmology and their potential solutions;  Connect observation with the need of a cosmological constant and describe dark energy.
