The evolution and appearance of a supernova remnant (SNR) can be greatly affected by the nature and makeup of the interstellar medium (ISM) into which the SNR is evolving. In this dissertation I examine how the multiphase nature of the ISM affects the evolution and appearance of a SNR. Multiwavelength observations consisting of high resolution images made in the radio, infrared, optical, and X-ray were obtained of the SNC IC 443. From these images and previous research done on IC 443, analytic and numerical hydrodynamics models have allowed assessment of various parameters.;The X-ray data indicate the age (;I find that IC 443 is evolving in a very complex region of the ISM. The intercloud medium into which the SNR is expanding os typical of a H II region (... |
