Likely to be interesting, hence the semi-liveblog.
Very good description of baryon acoustic oscillations and polarization.
Quick glimpse of stacked and normalized Planck measurements of tangential/radial polarization of cold/hot spots at ~ 1 degree scales.
Very nice lensing mass map from ~ first year of data.
Good summary of Sunyaev-Zeldovich effect.
And here come the cosmological parameters…
Same as this spring: tilted spectrum suggesting inflation; flat universe; 3 neutrino species, total mass under 0.23 eV; W = -1 +/- 0.2
Everything looks gaussian, slightly less dark energy than pre-Planck estimates, H0 still on the low side…
Þór is disturbed
Long discussion of correlation in the CMB with mass maps
nice signature of dark matter and that baryons are tracing dark matter distribution #ButWhyDoWeNeverTalkABoutBiasAnymore 😉
I ask about the H0 – HST key project/NGC4258 find it around 72 and Planck around 67
– word that the maser distances are coming down, big project to measure other extragalactic megamasers undwerway with prelim results pre-planck
NGC 4258 must have significant peculiar velocity relative to local flow (is my personal explanation – ought to be testable looking at surrounding attractors)
– 2.4% normalization offset between Planck and WMAP
source not yet understood, looks like some absolute calibration issue
looks worst at ~ 200 GHz
SPT data more consistent with Planck normalization
And now the anomalous spots… 2.5σ anomalies
maybe just function of looking for too many different anomalies… or cosmic variance… or…
