CMB Anisotropies: Observations

• expansion in spherical harmonics
• acoustic oscillations and acoustic peaks
• effect of cosmology and parameter determination
• COBE
• 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

CMB Foregrounds: Sunyaev-Zeldovich Effect

• thermal SZ physics:
  • Compton-y
  • frequency distortion
• SZ observations:
  • temperature maps: Coma cluster, clusters across redshifts, Abell 2319 across frequencies,
  • frequency spectrum
• SZ cosmological applications
  • South Pole Telescope survey image
  • Dark Energy Survey cluster followup

Dark Matter: Hot versus Cold

• hot and not
• effect on perturbation spectrum
