摘要：A master catalogue of hard X-ray sources has been compiled from the various surveys performed with the INTEGRAL/IBIS and SWIFT/BAT telescopes. This represents the 'hot' view of the universe. A 'cold' view of the universe has recently been given in the form of the Planck Early Release Compact Source catalogue. We compare the two skies and find that only very few sources are common to both catalogues. These are generally active galaxies, mainly Blazars and Seyfert 2's. The latter are probably detected due to a mixture of the AGN and ongoing starburst activity.
