This paper gives a comparison between likelihoods for the data - generally in agreement although for some parameters there is a systematic difference of 0.5sigma between likelihoods on the same data.pic.twitter.com/B7bOwB07At
Which is also shown in this figure, comparing the ’15 results to the ’18 ones (the systematic likelihood shift is the worst for the baryon density, and therefore the shift between different releases).pic.twitter.com/F7ZVaf0vzX
The low-z Hubble tension remains, now at 3.5sigma. The left hand plot shows H(z) - highlighting the redshift dependence of the tension (or throwing shade at Riess+). The Pantheon supernova sample + BBN aren’t in tension with H0, but adding lensing introduces tension there too.pic.twitter.com/b4xXycvAjH
This whopper of a figure shows that some tension remains between the high and low multipoles (red compared to light blue). This is the worst for the matter density and spectral index (and sigma8).pic.twitter.com/bTfMJGYc5n
This slightly more digestible figure shows how it is really the very low l < 30 (dotted line) that seems to be pulling the parameters away from the joint result.pic.twitter.com/Q2hgal64CZ
This figure shows the difference in the preferred ‘lensing’ of the temperature/polarisation compared to the reconstruction of lensing from the 4pt function. Strange that TE and EE (orange, green) want different lensing. Also dashed line differences between likelihoods scares me.pic.twitter.com/B2SHMPb5u9
This is a cool plot too: the lensing consistency parameter AL as compared to the predicted lensing deflection variance. The TT,TE,EE+lowE prefers 10% more lensing powerpic.twitter.com/7ty2cyi8bh
If we step away from systematics for a second, here’s a plot that asks what the difference in Neff would be taking the tension at face value. Low sigma8 —> low Neff, so Riess+ favours higher values of Neff/sigma8/H0 cc @physicsmattpic.twitter.com/0yB4at4iNP
When people ask how we know the universe is flat, show them this plot. Lensing (and BAO) just CRUSH the degeneracy (we were excited by this in @ACT_Pol when we release the first lensing results back in 2011!) #cosmology #astrotasticpic.twitter.com/rnwaev5xeQ
Also some nice plots exploring Neff and the sterile neutrino mass.The physical mass for a thermally-produced sterile neutrino is alone the gray lines, the Dodelson-Widrow equivalent on the thinner lines. The grey region is excluded (otherwise they’d look like DM)pic.twitter.com/fwpy6JrSdw
Is there a test?
Beautiful thread - thank you very much.
