Constraints on cosmology from the cosmic microwave background power spectrum measured by the Planck mission

Abstract : The Planck satellite has just released an exquisite full sky measurement of the microwave sky in 9 frequency bands. In particular, the temperature fluctuations in the cosmic microwave background (CMB) radiation have been observed with high sensitivity and angular resolution in the 100, 143 and 217 GHz channels. 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 six parameters LCDM model. I will review some of the cosmological results derived from the Planck CMB temperature power spectrum and, in particular, will discuss some of the implications regarding the Early Universe and neutrino physics.
