We present cosmological parameter results from the final full-mission Planck measurements of CMB anisotropies. find good consistency with standard spatially-flat 6-parameter $\Lambda$CDM cosmology having a power-law spectrum adiabatic scalar perturbations (denoted "base $\Lambda$CDM" in this paper), polarization, temperature, and lensing, separately combination. A combined analysis gives dark matter density $\Omega_c h^2 = 0.120\pm 0.001$, baryon $\Omega_b 0.0224\pm 0.0001$, spectral index...
We report on the implications for cosmic inflation of 2018 Release Planck CMB anisotropy measurements. The results are fully consistent with two previous cosmological releases, but have smaller uncertainties thanks to improvements in characterization polarization at low and high multipoles. temperature, polarization, lensing data determine spectral index scalar perturbations be $n_\mathrm{s}=0.9649\pm 0.0042$ 68% CL show no evidence a scale dependence $n_\mathrm{s}.$ Spatial flatness is...
The European Space Agency's Planck satellite, which was dedicated to studying the early Universe and its subsequent evolution, launched on 14 May 2009. It scanned microwave submillimetre sky continuously between 12 August 2009 23 October 2013, producing deep, high-resolution, all-sky maps in nine frequency bands from 30 857GHz. This paper presents cosmological legacy of Planck, currently provides our strongest constraints parameters standard model some tightest limits available deviations...

We describe the legacy Planck cosmic microwave background (CMB) likelihoods derived from 2018 data release. The overall approach is similar in spirit to one retained for 2013 and 2015 release, with a hybrid method using different approximations at low ( ℓ < 30) high ≥ multipoles, implementing several methodological data-analysis refinements compared previous releases. With more realistic simulations, better correction modelling of systematic effects, we can now make full use CMB...
We present measurements of the cosmic microwave background (CMB) lensing potential using final Planck 2018 temperature and polarization data. Using maps filtered to account for noise anisotropy, we increase significance detection in from 5 σ 9 . Combined with temperature, is detected at 40 an extensive set tests robustness lensing-potential power spectrum, construct a minimum-variance estimator likelihood over multipoles 8 ≤ L 400 (extending range lower compared 2015), which use constrain...
We analyse the Planck full-mission cosmic microwave background (CMB) temperature and E -mode polarization maps to obtain constraints on primordial non-Gaussianity (NG). compare estimates obtained from separable template-fitting, binned, optimal modal bispectrum estimators, finding consistent values for local, equilateral, orthogonal amplitudes. Our combined analysis produces following final results: f NL local = −0.9 ± 5.1; equil −26 47; ortho −38 24 (68% CL, statistical). These results...
Analysis of the Planck 2018 data set indicates that statistical properties cosmic microwave background (CMB) temperature anisotropies are in excellent agreement with previous studies using 2013 and 2015 releases. In particular, they consistent Gaussian predictions $Λ$CDM cosmological model, yet also confirm presence several so-called "anomalies" on large angular scales. The novelty current study, however, lies being a first attempt at comprehensive analysis statistics polarization signal...
We investigate constraints on cosmic reionization extracted from the Planck microwave background (CMB) data. combine CMB anisotropy data in temperature with low-multipole polarization to fit LCDM models various parameterizations of history. obtain a Thomson optical depth tau=0.058 +/- 0.012 for commonly adopted instantaneous model. This confirms, only anisotropies, low value suggested by combining 2015 results other sets and also reduces uncertainties. reconstruct history ionization fraction...
Using some of the latest cosmological datasets publicly available, we derive strongest bounds in literature on sum three active neutrino masses, $M_\nu$, within assumption a background flat $\Lambda$CDM cosmology. In most conservative scheme, combining Planck cosmic microwave (CMB) temperature anisotropies and baryon acoustic oscillations (BAO) data, as well up-to-date constraint optical depth to reionization ($\tau$), tightest $95\%$ confidence level (C.L.) upper bound find is...

These maps, at 100, 143, 217, 353 GHz, are early versions those that will be released final form later 2016. The improvements allow us to determine cosmic...
We present full-sky maps of the cosmic microwave background (CMB) and polarized synchrotron thermal dust emission, derived from third set Planck frequency maps. These products have significantly lower contamination instrumental systematic effects than previous versions. The methodologies used to derive these follow those described in earlier papers, adopting four methods (Commander, NILC, SEVEM, SMICA) extract CMB component, as well three GNILC, astrophysical components. Our revised...

We consider the case of very low reheating scenarios [${T}_{\mathrm{RH}}\ensuremath{\sim}\mathcal{O}(\mathrm{MeV})$] with a better calculation production relic neutrino background (with three-flavor oscillations). At 95% confidence level, lower bound on temperature ${T}_{\mathrm{RH}}>4.1\text{ }\text{ }\mathrm{MeV}$ is obtained from big bang nucleosynthesis, while ${T}_{\mathrm{RH}}>4.7\text{ Planck data (allowing masses to vary), most stringent date.

Using the Planck 2015 data release (PR2) temperature maps, we separate Galactic thermal dust emission from cosmic infrared background (CIB) anisotropies. For this purpose, implement a specifically tailored component-separation method, so-called generalized needlet internal linear combination (GNILC) which uses spatial information (the angular power spectra) to disentangle and CIB We produce significantly improved all-sky maps of emission, with reduced contamination, at 353, 545, 857 GHz.
