| dc.description | High-contrast peaks in the cosmic microwave background (CMB) anisotropy can appear as unresolved sources to observers. We fit simulated CMB maps generated with a cold dark matter model to a set of unresolved features at instrumental resolution 0.5 degrees to 1.5 degrees and present the integral density per steradian n(>|T|) of unresolved features brighter than threshold temperature |T|. A typical medium-scale experiment observing 0.001 sr at 0.5 degree resolution would expect to observe one unresolved feature brighter than 85 \muK after convolution with the beam profile, with less than 5% probability to observe a source brighter than 150 \muK. Increasing the power-law index of primordial density perturbations n from 1 to 1.5 raises these temperature limits |T| by a factor of 2. The results are only weakly dependent on the assumed values of the Hubble constant and baryon density. | |
