We use the temperature-gradient correlations induced by lensing … Planck is an ESA mission with significant NASA involvement. In their research, Geach and colleagues analysed the latest gravitational lensing map obtained by the Planck team, made public as part of the Planck Legacy Release in 2018, in combination with 200 000 quasars drawn from the largest sample ever compiled, the more than half-a-million quasars that comprise Data Release 14 of the Sloan Digital Sky Survey quasar catalogue. The Universe after Planck 2013 Martin BUCHER, Laboratoire Astroparticles & Cosmologie, Université Paris 7 (Denis-Diderot) for the PLANCK Collaboration 16 May 2013, IST Lisboa. 72.46.228.155 ( talk ) 20:58, 17 April 2013 (UTC) Planck was turned off on 23 October 2013. Planck has increased resolution and sensitivity compared to WMAP, and it observes in 9 bands instead of just 5. This paper presents the first cosmological results based on Planck measurements of the cosmic microwave background (CMB) temperature and lensing-potential power spectra. In my previous post, I mentioned CMB lensing and said that it was going to be a big thing. Here we present the minimum-variance (MV) lens reconstruction which forms the basis for the main results of Planck-2013-XVII. Gravitational lensing by large-scale structure Planck 2013 results. Papers II to X in the series describe the huge dataset obtained from the Planck satellite and released in March 2013. Here we present a detailed study of this effect, detecting lensing independently in the 100, 143, and 217 GHz frequency bands with an overall significance of greater than 25σ. Planck: Gravitational Lensing of the CMB Planck measures the lensing of the CMB by intervening matter, detecting the effect at greater than 25 sigma. (2013). Highlights from Planck 2013 cosmological results Paolo Natoli Università di Ferrara and ASI/ASDC DSU2013, Sissa, 17 October 2013 On behalf of the Planck collaboration . On the arcminute angular scales probed by Planck, the cosmic microwave background (CMB) anisotropies are gently perturbed by gravitational lensing. PR2 is described in the Planck 2015 Release Explanatory Supplement which is available via the ESA Planck Legacy Archive wiki page. Lensing map .

XVII. This is being recognized, and Planck is the key to all of this, so please do not try and take this observation away from Planck. Planck lensing power spectrum. Here's the 2013 rendition of the cosmological Mona Lisa, or, in our jargon, the multipole expansion of the Cosmic Microwave Background (CMB) power spectrum. Top: Planck spectra at 100, 143 and 217GHz without subtraction of foregrounds. (2013); statistical anisotropy of the primordial CMB fluctua-tions, as discussed inPlanck Collaboration XXIII(2013); and gravitational lensing, as discussed inPlanck Collaboration XVII (2013). This map is produced using a combination of the 143 and 217 GHz Planck maps on approximately 70% of the sky, and is the same map on which the Planck lensing likelihood is based.

The Planck lensing potential. Title: Planck 2013 results. The french magazine La Recherche announced that this year's astrophysics prize is awarded to the Planck article on gravitational lensing by large-scale structure, for the first full sky reconstruction of the CMB lensing effect. Clearly the large scale observations are actually "features" now, no longer "anomalies". 8% at Underlying question: conventional parameterization If you want to work on the edit constructively, please join in. If you want to read more about Planck, this is the official page, and this is the list of papers submitted as part of the 2013 release. We present cosmological parameter constraints based on a joint modeling of galaxy-lensing cross correlations and galaxy clustering measurements in the SDSS, marginalizing over small-scale modeling uncertainties using mock galaxy catalogs, without explicit modeling of galaxy bias. And indeed, CMB lensing has been presented as one of the main scientific results of the recent data release from the Planck Collaboration. JCAP09(2013)021 0:594 0:051, and 0:642 0:066, respectively. There are also aspects of the Planck analysis for which velocity e ects are believed to be negligible, but only if they are present at the expected level. Planck Public Data Release 1 (PR1) Mission Ancillary Data. • Planck strengths: large and redundent sky coverage, number of channels & detectors, low detector noise (25 x better than WMAP). Gravitational lensing creates tiny, additional distortions to the mottled pattern of the CMB temperature fluctuations. Some are replaced by newer products from PR2 (2015 release), see the PR2 Ancillary Data page. The constraints can be improved by 2%{15% if we further add the Planck lensing data into the analysis. Outline ... Planck Gravitational lensing spectrum. We present the implications for cosmic inflation of the Planck measurements of the cosmic microwave background (CMB) anisotropies in both temperature and polarization based on the full Planck survey, which includes more than twice the integration time of the nominal survey used for the 2013 release papers. The multi-frequency capability of the Planck satellite provides information both on the integrated history of star formation (via the cosmic infrared background, or CIB) and on the distribution of dark matter (via the lensing effect on the cosmic microwave background, or CMB).

From the Planck temperature data combined with Planck lensing, for this cosmology we find a Hubble constant, H 0 = (67.8 ± 0.9) km s -1 Mpc -1, a matter density parameter Ω m = 0.308 ± 0.012, and a tilted scalar spectral index with n s = 0.968 ± 0.006, consistent with the 2013 analysis.

Planck was a space observatory operated by the European Space Agency (ESA) from 2009 to 2013, which mapped the anisotropies of the cosmic microwave background (CMB) at microwave and infra-red frequencies, with high sensitivity and small angular resolution.The mission substantially improved upon observations made by the NASA Wilkinson Microwave Anisotropy Probe (WMAP). The Planck results for base LambdaCDM are in good agreement with baryon acoustic oscillation data and with the JLA sample of Type Ia supernovae. VII (2013), it is estimated in Planck Collaboration XVII (2013) that beam uncertainty leads to an e ff ective normalization uncer- tainty of approximately 0 . From the Planck temperature data combined with Planck lensing, for this cosmology we find a Hubble constant, H 0 = (67.8 ± 0.9) km s-1 Mpc-1, a matter density parameter Ω m = 0.308 ± 0.012, and a tilted scalar spectral index with n s = 0.968 ± 0.006, consistent with the 2013 analysis. gravitational lensing universal pressure assumed equal of maxBCG stacks profile of Arnaud (2010) Planck Collaboration 2011: PEP-XII Yet when sample is restricted to Rozo et al 2009 clusters which also appear in an X-ray selected sample, the discrepancy disappears Malmquist bias transferred from L. Perotto /12 47th ESLAB, 2013- 04-05, ESTEC Conclusions • integrated mass distribution on almost the full-sky using Planck (observational performancies + high systematic control in the data-processing) • Our fiducial lensing is based on a fsky 70% MV combination of the 143 and 217GHz However, as in the 2013 analysis, the amplitude of the fluctuation spectrum is found to be higher than inferred from some analyses of rich cluster counts and weak gravitational lensing. XVII. Resolution intermediate between WMAP (3 x better) and ACT, SPT. We find good consistency between lensing constraints and the results from the Planck CMB power spectra within the ΛCDM model. 2% and 143 and 217 GHz, and 0 . We present new constraints on the rest-frame sound speed, c_{eff}^2, and the viscosity parameter, c_{vis}^2, of the Cosmic Neutrino Background from the recent measurements of the Cosmic Microwave Background anisotropies provided by the Planck satellite. Fig.5. Planck lensing potential reconstruction (north and south galactic) Note –about half signal, half noise, not all structures are real map is effectively Wiener filtered. Compared to previous experiments, what distinguishes Planck is that it measures the power spectrum all the way from the largest angular scales down to less than 0.1 degrees.

We find that the Planck spectra at high multipoles (ℓ ≳ 40) are extremely well described by the standard spatially-flat six-parameter ΛCDM cosmology with a power-law spectrum of adiabatic scalar perturbations. We distribute: PHIBAR The Planck Public Data Release 2 (PR2) products are based on the complete mission which comprises data acquired between 13 August 2009 and 3 August 2013.
