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 present results based on full-mission Planck observations of temperature and polarization anisotropies the CMB. These data are consistent with six-parameter inflationary LCDM cosmology. From lensing data, for this cosmology we find a Hubble constant, H0= (67.8 +/- 0.9) km/s/Mpc, matter density parameter Omega_m = 0.308 0.012 scalar spectral index n_s 0.968 0.006. (We quote 68% errors measured parameters 95% limits other parameters.) Combined LFI measurements lead to reionization optical...
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...
The Simons Observatory (SO) is a new cosmic microwave background experiment being built on Cerro Toco in Chile, due to begin observations the early 2020s. We describe scientific goals of experiment, motivate design, and forecast its performance. SO will measure temperature polarization anisotropy six frequency bands: 27, 39, 93, 145, 225 280 GHz. initial configuration have three small-aperture 0.5-m telescopes (SATs) one large-aperture 6-m telescope (LAT), with total 60,000 cryogenic...

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...
This paper presents the Planck 2015 likelihoods, statistical descriptions of 2-point correlations CMB data, using hybrid approach employed previously: pixel-based at $\ell<30$ and a Gaussian approximation to distribution spectra higher $\ell$. The main improvements are use more better processed data polarization detailed foreground instrumental models, allowing further checks enhanced immunity systematics. Progress in modelling enables larger sky fraction. Improvements processing models...
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 present the science case, reference design, and project plan for Stage-4 ground-based cosmic microwave background experiment CMB-S4.
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.
