Abstract

The Planck satellite has surveyed the whole sky for more than four times. The nominal mission of two full sky surveys is to be released to the public in early 2013. The study of clusters of galaxy from their inprint on the cosmic microwave background, i.e., the Sunyaev-Zel'dovich effect, allows to investigate the formation and the evolution of large scale structures as well as to constrain cosmology as this population of objects is tightly linked to the contant in matter and energy of the Universe. From the first all-sky survey, we have released an early SZ sample of 189 clusters detected via the Sunyaev-Zel'dovich effect with high signal-to-noise and is highly reliable, and since presented the detection of about 50 new clusters found by Planck. The Planck collaboration is engaged in massive identification and follow-up programs of its SZ sources at X-ray, optical, and SZ wavelengths. We will review the status of the curretn results in terms of detection, validation and physical characterisation of clusters in the Planck survey.
