Abstract

Submillimetre galaxies are an important element in the history of the universe. There have been great advances in technology in the last ten years that have enabled deeper and more detailed investigations of these distant objects. In thisthesis I describe investigations of the properties of high redshift submillimetre galaxies made using data from multiple surveys and multiple instruments. Firstly I describe the process involved in reducing AzTEC data to produce images. I then present the reduced maps and compare them, along with a source catalogue, to those produced by the AzTEC instrument team. I found both reductions produce broadly similar results with some differences that can be explained by slightly different sets of input maps. I then present an analysis of the fainter objects in one of the AzTEC fields using a stacking technique. This analysis determines the contribution Spitzer detected galaxies make to the background at 1.1mm, the redshift dependence of this contribution and the average dust mass that can be associated with it. I also describe an analysis of the ux ratios Eales et al. (2003)found using the available AzTEC data and Spitzer IRAC imaging. In the the penultimate chapter I describe the frequentist identification technique I used to determine counterparts to SCUBA submillimetre sources in the CUDSS three hour field using Spitzer infrared data.
