CMB Anisotropies: Observations

• expansion in spherical harmonics
• acoustic oscillations and acoustic peaks
• effect of cosmology and parameter determination
• COBE
• interregnum
• WMAP: temperature anisotropy power spectrum
• Planck:
  • movies: a photon's journey, revealing the CMB
  • frequency bands
  • scanning animation, one strip, all-sky maps at different frequencies
  • all sky temperature map; power spectrum
  • Planck vs WMAP

CMB Polarization

• theory--intermediate, advanced: why and how is the CMB polarized?
• polarization signatures: hot and cold spots
• WMAP: polzarized CMB sky
• BICEP2: B mode map, power spectrum

Horizons, Structure, and the Power Spectrum

• structure growth: a characteristic scale
• transfer function
• implications for the power spectrum
