WMAP year 3 highlights

Ooh. l=2 anomaly is still there. Could be just Cosmic Variance
Apparently the "red" and "green" curves have lots of "scientific" information"!
Nice third acoustic peak...

WMAP year 3 data release is out.

Instant highlights:

Page et al - Polarzation analysis - no B modes. Ω_GW h² < 10^-12 (95%) with r < 0.55 which is approaching the level where some simpler inflation models are ruled out, but not quite.

Hinshaw et al - Temperature - τ ~ 0.088, n = 0.95 +/- 0.02 - be interesting if this is really significantly different from unity

Spergel et al - The Fun Paper - w = -0.97 +0.07 - 0.09 (ie it is = -1!)
Ω = 1 Big Rip is probably ruled out now...


Ω_Λ = 0.72 +/- 0.04

redshift of reionization is 12-24, optimal ~ 15 !!!

Dark Matter is non-baryonic

Either there is slight breach of scale invariance, or tensor modes are significant after all, need to read carefully to figure out why they are saying this.
