Title:Radio frequency foreground emission and the separation of microwave anisotropies from foreground contamination

Abstract: The effects on CMB measurements of foreground contamination due to synchrotron radiation, free-free emission and discrete sources are considered. Estimates of the level and power spectrum of the Galactic fluctuations are made using low frequency maps and recent Tenerife data. New methods for achieving a frequency-based separation of Galactic and CMB components are discussed, and a positive/negative maximum entropy algorithm shown to be particularly powerful in this respect.
