Planck and the cosmic microwave background


One of the year's world-wide science highlights was the announcement of first cosmic microwave background results from the European Planck satellite in March 2013. The most cited publication of the Planck Collaboration "Planck 2013 results. XVI. Cosmological parameters, arXiv:1303.5076" had collected 1117 citations by the end of 2013 already before its final publication in Astronomy and Astrophysics, 2014.

Both our cosmologists and astronomers are actively participating in the scientific analysis of Planck observations. The most important contribution of our experimental cosmology group has been the production of the sky maps for the three Low Frequency Instrument (LFI) frequencies (30, 44 and 70 GHz) as well as a number of related tasks, including null tests on the maps, estimation of their residual noise correlations, and producing large Monte Carlo simulations (at CSC - IT Center for Science in Finland) of the data. We have also contributed to development of improved calibration methods for LFI and fitted cosmological models of primordial isocurvature perturbations to Planck data.
