The multi-wavelength, multi-temporal (blazar) sky

Abstract. Data from different observational facilities, operating at all wavelengths across the electromagnetic spectrum and taken in different periods, is becoming increasingly available. I will show how new VO based tools, currently under development at ASDC and elsewhere, help users to exploit the potential of richer and richer multi-frequency astronomical archives. As a specific example I will present the results of a Planck, Swift and Fermi campaign to simultaneously observe samples of blazars from radio to high-energy gamma-rays and a new simplified scenario for the interpretation of the diverse observational properties that blazars exhibit in different energy bands.
