ToK Warszawa meeting - Rough Notes Sat 17 Feb 2007

These are just rough notes - feel free to correct them, add links, etc.

Ruth Durrer - CMB

- general CMB presentation

Challinor & Lewis 2006 - lensing effect on C_l spectrum - AstroPh:0601594 especially 500 < l < 3000

- lensed polarisation signals E \gg  B \gg_{l>10} B_{tensor}

- observed WMAP polarisation e.g. Spergel et al. 2005, CBI - Readhead et al. 2004, Page et al. 2006 - compilation, detection around 200-400 = l, oscillations expected (observational estimates exist with very big error bars) around 400-800 = l

- tensor spectrum - gravity waves - B modes of the polarisation - if these were unexpectedly large, then this could be the "smoking gun" of inflation

WMAP + ... : \Rightarrow n_s \sim 0.95 \pm 0.05-0.10, r < \sim 0.4

- SDSS LRG (luminous red galaxies) + WMAP 3 \Rightarrow \Omega_{tot} = 1.003 \pm 0.010 according to Tegmark et al. 2006

  • What is dark matter?
  • What is dark energy?
  • What is the inflaton?
