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.

In the first half of the module students learn to use Python for scientific applications. Python is an interpreted, high-level, general-purpose programming language that can be used for a range of academic and research based activities including high level mathematics and data processing work. Python is widely used in commercial and research environments. This is followed by a two week introduction to LaTeX for typesetting high-quality reports.

The second half 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.
