Synchrotron Radiation as CMB Foreground
Abstract
Description
Synchrotron emission is an important process in Galactic dynamics and a potentially confusing foreground for cosmic microwave background (CMB) radiation observations. Though the mechanism of synchrotron emission is well understood, the details for the Galaxy and many external sources are not well characterized. Quality maps at multiple frequencies are lacking but needed for a full understanding of the Galactic synchrotron emission, including intensity, spectrum, and spectral variation. At high frequencies (> 70 GHz) synchrotron emission is not a severe limitation to precise CMB observations well away from the Galactic plane.
