title: "Signals from the cosmological recombination era and spectral distortions of the CMB"

abstract:
It was realized that small changes in the cosmological ionization history caused by previously neglected physical processes affect the CMB power spectra at a level that will be noticeable in the analysis of data from the Planck satellite.
In my talk I will review recent calculations of the cosmological recombination problem trying to convince everyone that at this point all important processes have been identified and are under control. I will also demonstrate that photons emitted during the recombination epochs lead to interesting deviations of the CMB energy spectrum from a blackbody, which in the future might open another way to learn about the infant Universe. Especially if something non-standard occurred at early times, the CMB energy spectrum may be the only ways to learn about this.
