We present the first search for spinning dust emission from a sample of 34Galactic cold cores, performed using the CARMA interferometer. For each of ourcores we use photometric data from the Herschel Space Observatory to constrainN_{H}, T_{d}, n_{H}, and G_{0}. By computing the mass of the cores andcomparing it to the Bonnor-Ebert mass, we determined that 29 of the 34 coresare gravitationally unstable and undergoing collapse. In fact, we found that 6cores are associated with at least one young stellar object, suggestive oftheir proto-stellar nature. By investigating the physical conditions withineach core, we can shed light on the cm emission revealed (or not) by our CARMAobservations. Indeed, we find that only 3 of our cores have any significantdetectable cm emission. Using a spinning dust model, we predict the expectedlevel of spinning dust emission in each core and find that for all 34 cores,the predicted level of emission is larger than the observed cm emissionconstrained by the CARMA observations. Moreover, even in the cores for which wedo detect cm emission, we cannot, at this stage, discriminate between free-freeemission from young stellar objects and spinning dust emission. We emphasisethat, although the CARMA observations described in this analysis placeimportant constraints on the presence of spinning dust in cold, denseenvironments, the source sample targeted by these observations is notstatistically representative of the entire population of Galactic cores.
