Abstract

The Planck mission has clearly demonstrated that, although not specifically designed for the observation of extragalactic sources, the space-borne experiments aimed at investigating the Cosmic Microwave Background (CMB) have the potential to bring breakthrough science also in this field. One example is the detection of high-z galaxies with extreme gravitational amplifications. The combination of flux boosting and of stretching of the images has allowed the investigation of the structure of galaxies at z ⋍ 3 with the astounding spatial resolution of ⋍ 60 pc. Another example is the detection of proto-clusters of dusty galaxies at high z, when they may not yet possess the hot intergalactic medium allowing their detection in X-rays or via the Sunyaev-Zeldovich effect.
