Abstract:

The Cambridge Cosmic Anisotropy Telescope (CAT) has recently made the first detailed image of primordial anisotropies in the cosmic microwave background (CMB) radiation at 15 GHz. Preliminary results from CAT observations of a second

field are presented here. These new data show excess power on angular scales of spherical harmonic multipoles

(i.e. around half a degree), at levels consistent with the first published detection. These two results mark the downturn in the CMB power spectrum establishing the presence of the first Doppler peak, and by constraining its position also limit values of
