Foregrounds and Forecasts for the Cosmic Microwave Background

  title={Foregrounds and Forecasts for the Cosmic Microwave Background},
  author={Max Tegmark and Daniel J. Eisenstein and Wayne Hu and Angelica de Oliveira-Costa},
One of the main challenges facing upcoming cosmic microwave background (CMB) experiments will be to distinguish the cosmological signal from foreground contamination. We present a comprehensive treatment of this problem and study how foregrounds degrade the accuracy with which the Boomerang, MAP, and Planck experiments can measure cosmological parameters. Our foreground model includes not only the normalization, frequency dependence, and scale dependence for each physical component, but also… CONTINUE READING
