Scientific paper

ESA's Planck satellite, in addition to improving anisotropy measurements of the CMB, will perform an all-sky, low resolution, survey in nine bands from 30 to 857 GHz, and is expected to detect a large sample of extragalactic radio sources. We propose the observation of a sample of selected objects simultaneously with the Planck satellite in three pairs of 2-GHz-wide channels from 4.5 to 44 GHz and in a channel at 1.4 GHz. These observations will provide information useful for reconstructing the SED across the radio and FIR bands in several epochs to investigate the properties of populations, and improving the models that describe the physics of sources, and values of flux density and polarization useful for Planck calibration, and to quantify the quality of the source detection techniques applied to the Planck maps. The satellite, launched on May the 14th, should begin collecting data on July the 28th. We ask for 4 hours a week to observe a sample of 300 objects, during, at least, two complete sky surveys of the satellite, i.e. 12 months. For this reason we ask that continuing status be allocated to this project.
