We analyze the final release of the Planck satellite data to constrain the gravitational lensing potential in a model-independent manner. The amount of lensing determined from the smoothing of the acoustic peaks in the temperature and polarization power spectra is 2σ too high when compared with the measurements using the lensing reconstruction and 2.8σ too high when compared with ΛCDM expectation based on the "unlensed" portion of the temperature and polarization power spectra. The largest change from the previous data release is the ΛCDM expectation, driven by improved constraints to the optical depth to reionization. The anomaly still is inconsistent with actual gravitational lensing, given that the lensing reconstruction constraints are discrepant independent of the model. Within the context of ΛCDM, improvements in its parameter constraints from lensing reconstruction brings this tension to 2.1σ and from further adding baryon acoustic oscillation and Pantheon supernova data to a marginally higher 2.2σ. Once these other measurements are included, marginalizing this lensing-like anomaly cannot substantially resolve tensions with lowredshift measurements of H0 and S8 in ΛCDM, ΛCDM+N eff or ΛCDM+ mν ; furthermore the artificial strengthening of constraints on mν is less than 20%.

“…The frequency spectrum is known with great accuracy [46]. Measurements of the power spectrum of CMB anisotropies in temperature are cosmic-variance limited down to very small scales (ℓ ∼ 1, 500) and the quality of current CMB data in polarization is already good enough to tighten constraints on cosmological parameters [14,16,17,19,20]. The next generation of CMB experiments will further improve our knowledge of CMB polarization anisotropies [21,[30][31][32][33].…”

“…Measurements of the CMB anisotropies from the Planck satellite have put the tightest constraints ever on cosmological parameters from a single experiment [14], dramatically improving the constraints from the predecessor satellite WMAP [15]. From the ground, the Atacama Cosmology Telescope (ACT) polarization-sensitive receiver and the South Pole Telescope (SPT) have been measuring with incredible accuracy CMB anisotropies at the smallest scales in temperature and polarization [16,17]. At degree and subdegree scales, the BICEP/Keck collaboration [18,19] and the POLARBEAR telescope [20] are looking at the faint CMB "B-mode" signal, containing information about both the early stages of the Universe (primordial B-modes) and the late time evolution (lensing B-modes).…”

Status of Neutrino Properties and Future Prospects—Cosmological and Astrophysical Constraints

2018

View full text Add to dashboard Cite

Cosmological observations are a powerful probe of neutrino properties, and in particular of their mass. In this review, we first discuss the role of neutrinos in shaping the cosmological evolution at both the background and perturbation level, and describe their effects on cosmological observables such as the cosmic microwave background and the distribution of matter at large scale. We then present the state of the art concerning the constraints on neutrino masses from those observables, and also review the prospects for future experiments. We also briefly discuss the prospects for determining the neutrino hierarchy from cosmology, the complementarity with laboratory experiments, and the constraints on neutrino properties beyond their mass.

“…Another peculiarity in the data is that cosmological parameters estimated from small scales (CMB multipoles l ≳ 1000) are somewhat offset relative to the values estimated from large scales (l ≲ 1000) [26][27][28][29]. In particular, larger scales show some preference for a higher Hubble constant.…”

Vacuum phase transition solves the H0 tension

Taking the Planck cosmic microwave background data and the more direct Hubble constant measurement data as unaffected by systematic offsets, the values of the Hubble constant H 0 interpreted within the ΛCDM cosmological constant and cold dark matter cosmological model are in ∼3.3σ tension. We show that the Parker vacuum metamorphosis (VM) model, physically motivated by quantum gravitational effects and with the same number of parameters as ΛCDM, can remove the H 0 tension and can give an improved fit to data (up to a mean Δχ 2 ¼ −7.5). It also ameliorates tensions with weak lensing data and the high redshift Lyman alpha forest data. Considering Bayesian evidence, we found in the case of the Planck data set alone positive evidence for a VM model against a cosmological constant both in the six-and nine-parameter framework. When the R16 data set is also considered, we found a strong evidence for the VM model against a cosmological constant in nine-parameter space. We separately consider a scale-dependent scaling of the gravitational lensing amplitude, such as provided by modified gravity, neutrino mass, or cold dark energy, motivated by the somewhat different cosmological parameter estimates for low and high CMB multipoles. We find that no such scale dependence is preferred.
