Cosmic Background Radiation: Components in Other Wavelength Ranges and Their Relevance to Microwave Background
Abstract
The background radiation is usually contaminated by local components of galactic and solar system origins. The local components can be separated out of the cosmological component by utilizing their anisotropies in different wavelength ranges, and their contributions to spatial fluctuations are comparable to the upper limits observed to date. The cosmological components in different wavelength ranges are genetically related to each other. Models for explaining the submillimeter excess predict the background radiation in other ranges, such as in the infrared and X-ray ranges. The X-ray background is discussed by reference to recent results obtained by Ginga.
