The CBI allows imaging, in both total intensity and polarization, of a wide range of Galactic phenomena on angular scales of 5-30 arcmin, in the relatively unexplored frequency range 26-36 GHz. We have made observations of a variety of objects and regions in the Galaxy; these include molecular dust clouds, supernova remnants and HII regions. By utilizing 10 1-GHz channels and polarization imaging capability we investigate the nature of the Galactic emissions (synchrotron and free-free emission) and in particular, the anomalous dust-correlated emission whose origin remains elusive. Detailed comparisons are made with multi-frequency data to provide further spectral and morphological information on the diffuse Galactic emissions which are important CMB foregrounds, particularly for polarization studies. The relevance of these results for current and future CMB experiments is discussed.
