text:   Tension?",6,"['My new paper looking at Hubble constant constraints from CMB E-mode data sets: <LINK>\n\nRecently, the @SPTelescope paper Dutcher+ showed that Planck, ACTPol, SPTpol &amp; SPT-3G all get higher H0 in EE than the Planck TT LCDM constraint (see their Fig 13). [1/6] <LINK>', 'What happens if we *combine* the different EE spectra? Does this reinforce the preference for a higher H0? If yes, perhaps it could be some clue that to resolve the Hubble tension we want a model that departs from LCDM more strongly in temperature than polarization. [2/6]', 'I ran the fit… and found that combining Planck EE + ACTPol EE + SPTpol EE actually gives 68.7 +/- 1.3 km/s/Mpc, 2.4 sigma lower than the latest SH0ES distance ladder (73.2 +/- 1.3).\n\nSo how can you combine three values that are all &gt;=70 and get 68.7? [3/6]', 'The answer lies in the different degeneracy directions across the full LCDM param space (look at n_s vs Obh2), related to sensitivity to different multipole ranges. To reach a consensus on Obh2 between Planck and ACTPol/SPTpol you end up shifting lower in H0, n_s. [4/6] https://t.co/m620SQwkiN', 'Are the constraints from different EE data sets consistent with one another? Yes - difference at most 1.4 sigma across the LCDM space (see Table 2). Also consistent with Planck TT LCDM at 0.8 sigma. [5/6] https://t.co/fOeSK26c9b', 'NB - The SPT-3G likelihood isn’t public yet, but since the degeneracy directions are going to be pretty similar between SPTpol and SPT-3G EE I expect that combining Planck EE + SPT-3G EE will similarly lead to a lower H0 / lower n_s.
