A study of the infrared emission of galactic supernova remnants

This work aims to investigate the nature of the infrared (IR) emission of supernova remnants (SNRs), and to use this radiation to reveal the physical properties of SNRs and the gas and dust they contain. This project has been made possible only recently, following the success of the Infrared Astronomical Satellite (IRAS) in 1983. The first part of this thesis attempts to find the general characteristics of the IR emission of SNRs. A survey of the known galactic SNRs in the IRAS database has been completed. It is found that only one third of the galactic SNRs show detectable IR emission. Many remnants are confused with other galactic IR sources. The youngest SNRs exhibit spectra of relatively warm dust at $\sim$90 K. Older SNRs, exhibit spectra that indicate dust grains within the SNRs have temperatures spanning a range from $\sim$150 K to $\sim$30 K. Supernova remnants can not be distinguished from other galactic IR sources on the basis of their IR colors alone.
