Isocurvature fluctuations in the effective Newton's constant
D. Paoletti, M. Braglia, F. Finelli +2
We present a new isocurvature mode present in scalar-tensor theories of gravity that corresponds to a regular growing solution in which the energy of the relativistic degrees of fr…
Planck 2018 results. III. High Frequency Instrument data processing and frequency maps
Planck Collaboration, N. Aghanim, Y. Akrami +152
This paper presents the High Frequency Instrument (HFI) data processing procedures for the Planck 2018 release. Major improvements in mapmaking have been achieved since the previou…
Reionization in the dark and the light from Cosmic Microwave Background
Dhiraj Kumar Hazra, Daniela Paoletti, Fabio Finelli +1
We explore the constraints on the history of reionization from Planck 2015 Cosmic Microwave Background (CMB) data and we derive the forecasts for future CMB observations. We consid…
Planck 2018 results. XII. Galactic astrophysics using polarized dust emission
Planck Collaboration, N. Aghanim, Y. Akrami +160
We present 353 GHz full-sky maps of the polarization fraction , angle , and dispersion of angles of Galactic dust thermal emission produced from the 2018 release of Planc…
Planck 2018 results. X. Constraints on inflation
Planck Collaboration, Y. Akrami, F. Arroja +173
We report on the implications for cosmic inflation of the 2018 Release of the Planck CMB anisotropy measurements. The results are fully consistent with the two previous Planck cosm…
Planck 2018 results. VIII. Gravitational lensing
Planck Collaboration, N. Aghanim, Y. Akrami +155
We present measurements of the cosmic microwave background (CMB) lensing potential using the final 2018 temperature and polarization data. We increase the signifi…
Planck 2018 results. VI. Cosmological parameters
Planck Collaboration, N. Aghanim, Y. Akrami +179
We present cosmological parameter results from the final full-mission Planck measurements of the CMB anisotropies. We find good consistency with the standard spatially-flat 6-param…
Planck 2018 results. IV. Diffuse component separation
Planck Collaboration, Y. Akrami, M. Ashdown +150
We present full-sky maps of the cosmic microwave background (CMB) and polarized synchrotron and thermal dust emission, derived from the third set of Planck frequency maps. These pr…
Planck 2018 results. II. Low Frequency Instrument data processing
Planck Collaboration, Y. Akrami, F. Argüeso +148
We present a final description of the data-processing pipeline for the Planck, Low Frequency Instrument (LFI), implemented for the 2018 data release. Several improvements have been…
Planck 2018 results. I. Overview and the cosmological legacy of Planck
Planck Collaboration, Y. Akrami, F. Arroja +188
The European Space Agency's Planck satellite, which was dedicated to studying the early Universe and its subsequent evolution, was launched on 14 May 2009. It scanned the microwave…
Improved CMB anisotropy constraints on primordial magnetic fields from the post-recombination ionization history
D. Paoletti, J. Chluba, F. Finelli +1
We investigate the impact of a stochastic background of Primordial Magnetic Fields (PMF) generated before recombination on the ionization history of the Universe and on the Cosmic…
The primordial magnetic field in our cosmic backyard
Sebastian Hutschenreuter, Sebastian Dorn, Jens Jasche +4
We reconstruct the 3D structure of magnetic fields, which were seeded by density perturbations during the radiation dominated epoch of the Universe and later on were evolved by str…
Planck 2018 results. XI. Polarized dust foregrounds
Planck Collaboration, Y. Akrami, M. Ashdown +131
The study of polarized dust emission has become entwined with the analysis of the cosmic microwave background (CMB) polarization. We use new Planck maps to characterize Galactic du…
