Constraints on cosmology from the Planck CMB sky
Laboratoire de l'accélérateur linéaire, Orsay
The Planck satellite has just released an exquisite full sky measurement of the temperature fluctuations in the cosmic microwave background (CMB) with high sensitivity and angular resolution. The CMB power spectrum is among the most informative and robust probes in cosmology. Its recent measurement with cosmic variance precision over a wide range of angular scales by the Planck mission has provided a stress test for the standard LCDM model. I will review some of the cosmological results derived from the Planck power spectrum and some of the techniques used for parameters estimation.
