POST-PUBLICATION EDIT: actually a connection between a related model of renormalizable long-range vector-mediated neutrino self-interactions, the XENON excess, and the H0 tension, was made in 2006.11919, based on an UV complete model discussed earlier in the context of the H0 tension e.g. in 2004.13039.

We also examine the possibility of addressing the H-0 and sigma(8) tensions, finding that only the former can be partially alleviated. Finally, we perform a Bayesian model comparison analysis to quantify the possible preference for the two IDE models against the standard concordance ACDM model, finding that the latter is always preferred with the strength of the evidence ranging from positive

Sigma8 tension

The well-known tensions on the cosmological parameters $$H_0$$ and $$\sigma _8$$ within the $$\Lambda $$ CDM cosmology shown by the Planck-CMB and LSS data are We also examine the possibility of addressing the H-0 and sigma(8) tensions, finding that only the former can be partially alleviated. Finally, we perform a Bayesian model comparison analysis to quantify the possible preference for the two IDE models against the standard concordance ACDM model, finding that the latter is always preferred with the strength of the evidence ranging from positive to very strong. We present a model describing the dark sector (DS) featured by two interactions remaining efficient until late times in the matter-dominated era after recombination: the interaction among dark radiations (DR), and the interaction between a small fraction of dark matter and dark radiation. The dark sector consists of (1) a dominant component cold collisionless DM (DM1), (2) a sub-dominant cold To reconcile the current tensions between high and low redshift observations, we perform the first constraints on the Finslerian cosmological models including the effective dark matter and dark energy components.

The reduction to 3 line levels also means that the SIGMA 8 can be more The ΛCDM (Lambda cold dark matter) or Lambda-CDM model is a parameterization of the Big Bang cosmological model in which the universe contains three major components: first, a cosmological constant denoted by Lambda (Greek Λ) and associated with dark energy; second, the postulated cold dark matter (abbreviated CDM); and third, ordinary matter. If the Higgs vacuum expectation value $v$ in early universe is $\sim 1 \%$ higher than its present value $v_0=246$ GeV, the $^7$Li puzzle in BBN and the CMB/$\Lambda The uncertainty on measurements, given by the Heisenberg principle, is a quantum concept usually not taken into account in General Relativity. From a cosmological point of view, several authors wonder how such a principle can be reconciled with the Big Bang singularity, but, generally, not whether it may affect the reliability of cosmological measurements.

Perhaps the most convincing one is related to sigma8, a measure of the clumpiness of the LSS, defined by the rms variance of the matter density field on a 8 Mpc/ h scale: sigma8 governs the amplitude of the matter power spectrum P (k), and it is customary to compare it …

sigma_8 is usually quite stable against extensions to LCDM (opposite of curvature and H0), one exception are massive neutrinos (and I guess stuff like decaying DM, Dick mentions fuzzy DM) Sources of tension: sigma_8 from clusters, some tension with Websky Compton-y map

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.
