Description

This module is practically based with comprehensive work sheets for each session and demonstrators available to answer any queries that may arise. Students are encouraged to work at their own speed depending on their previous experience. Students with no prior experience will need to spend more time than their more experienced counterparts outside the class sessions to complete the assignments contained in the work sheets.

Students first learn to produce high-quality typeset reports using LaTeX and a stylesheet. This is followed by an introduction to the GNU Octave numerical mathematics package. The Octave language is essentially the same as the MATLAB™ language which is widely used in commercial and research environments for numerical modelling. The final part introduces students to computer-aided manipulation and analysis of modern astrophysical data. They will gain an understanding of the basic properties of digital imaging and spectroscopy data and how such data are limited by various noise components added in the signal chain between the astrophysical source and the detection of photons or waves from it. The students will gain an appreciation of the computer tools and algorithms used to analyse astrophysical data through a series of short projects based on actual data, with the goal of producing meaningful scientific results and understanding the uncertainties associated with them. The module also illustrates the interesting differences of approach needed by 'observational physics' as opposed to 'experimental physics'.

Module Aims

Every physicist must be able to analyse data, evaluate theoretical models, and present their work in the form of a technical report. They must also be able to perform investigations, such as experiments, and solve the problems they encounter in a systematic and logical manner.
