It almost sounds like Adam is speaking in time  Stimulated by the sigma_8 tension that the sigma_8 value derived from LSS measurements is ~ 3\sigma lower than that derived from CMB assuming LCDM, there have been many discussions about the signatures of new physics, e.g. interacting dark sector.

We use two different samples of BAO data, which are obtained using two-point spatial (BAO 2PCF) and angular (BAO 2PACF) correlation functions. The new discrepancy—called the sigma-eight tension—involves measuring the density of matter in the universe and the degree to which it is clumped up, as opposed to being uniformly distributed 2019-09-13 SigmaÅtta är en matematiktävling för skolklasser i Sverige och i de nordiska länderna.

Sigma8 tension

We find that the well known tension in $\sigma_8$ between Planck CMB and large scale structure (LSS) observations is (1) exacerbated in the HS model and (2) somewhat alleviated in the DDE model. We The new discrepancy—called the sigma-eight tension—involves measuring the density of matter in the universe and the degree to which it is clumped up, as opposed to being uniformly distributed. The While longitudinal stabilisation was satisfactory, the processed Si tends to have a transverse curvature which is difficult to control sufficiently well by the spring tension. Alternative solutions consisting of semi-supported options (e.g. Si/Be) are presently under study, which should yield better overall stability.

A partial cause for this reduced tension is the fact that more recent data tend to probe higher redshifts (with higher errorbars) where there is degeneracy among different models due to matter domination. Abstract. The introduction of Dark Matter-neutrino interactions modifies the Cosmic Microwave Background (CMB) angular power spectrum at all scales, thus affecting the reconstruction of the cosmological parameters. 1205-1215 Lewis & Bocquet: What is the state of sigma8 tension?

Korten skall läggas så att summan av kortens värde är densamma på alla fyra sidorna 2019-09-13 · This model can efficiently fit observations solving the two tensions. To our knowledge, this is the first time where a modified gravity theory can alleviate both $H_0$ and $\sigma_8$ tensions simultaneously, hence, offering an additional argument in favor of gravitational modification. 2014-09-09 · This is, however, at the expense of a degraded fit to $Planck$ temperature data, and we quantify the residual tension at $2.5\sigma$ and $1.6 \sigma$ for massive and sterile neutrinos respectively.
