High-latitude galactic emission and the search for anisotropies of the cosmic background radiation

The anisotropies of the diffuse radiation in the mm and sub-mm spectral region are studied. These are produced by insterstellar dust emission and radio continuum emission, and can contaminate the measurements of the cosmological background anisotropies. Two high Galactic latitude cosmological windows permit searches for cosmic background radiation anisotropies at a level of Delta-T/T of about 10 to the -6th, at angular scales between about 0.5 and 5 deg, in the spectral interval between 2 and 9/cm. 23 refs
