A high-resolution self-consistent whole sky foreground model
Qizhi Huang, Fengquan Wu, Xuelei Chen
The neutral hydrogen 21cm line is potentially a very powerful probe of the observable universe, and a number of on-going experiments are trying to detect it at cosmological distanc…
Core Cosmology Library: Precision Cosmological Predictions for LSST
Nora Elisa Chisari, David Alonso, Elisabeth Krause +27
The Core Cosmology Library (CCL) provides routines to compute basic cosmological observables to a high degree of accuracy, which have been verified with an extensive suite of valid…
Magnetizing the Cosmic Web during Reionization
Mathieu Langer, Jean-Baptiste Durrive
Increasing evidence suggests that cosmological sheets, filaments, and voids may be substantially magnetized today. The origin of magnetic fields in the intergalactic medium (IGM) i…
The Atacama Cosmology Telescope: Two-season ACTPol Extragalactic Point Sources and their Polarization properties
Rahul Datta, Simone Aiola, Steve K. Choi +30
We report on measurements of the polarization of extragalactic sources at 148 GHz made during the first two seasons of the Atacama Cosmology Telescope Polarization (ACTPol) survey.…
Secondary CMB anisotropies from magnetized halos --I: Power spectra of the Faraday rotation angle and conversion rate
Nadège Lemarchand, Julien Grain, Guillaume Hurier +2
Magnetized plasmas within halos of galaxies leave their footprint on the polarized anisotropies of the cosmic microwave background. The two dominant effects for astrophysical halos…
Spitzer Planck Herschel Infrared Cluster (SPHerIC) survey: Candidate galaxy clusters at 1.3 < z < 3 selected by high star-formation rate
C. Martinache, A. Rettura, H. Dole +17
There is a lack of large samples of spectroscopically confirmed clusters and protoclusters at high redshifts, 1.5. Discovering and characterizing distant (proto-)clusters is im…
The bispectra of galactic CMB foregrounds and their impact on primordial non-Gaussianity estimation
Gabriel Jung, Benjamin Racine, Bartjan van Tent
We use the binned bispectrum estimator to determine the bispectra of the dust, free-free, synchrotron, and AME galactic foregrounds using maps produced by the Commander component s…
Measurements of the Cross Spectra of the Cosmic Infrared and Microwave Backgrounds from 95 to 1200 GHz
M. P. Viero, C. L. Reichardt, B. A. Benson +40
We present measurements of the power spectra of cosmic infrared background (CIB) and cosmic microwave background (CMB) fluctuations in six frequency bands. Maps at the lower three…
Affleck-Dine baryogenesis via mass splitting
Eugeny Babichev, Dmitry Gorbunov, Sabir Ramazanov
We introduce a class of non-supersymmetric models explaining baryogenesis a la Affleck-Dine, which use a decay of two superheavy scalar fields with close masses. These scalars acqu…
Fast and easy super-sample covariance of large scale structure observables
Fabien Lacasa, Julien Grain
We present a numerically cheap approximation to super-sample covariance (SSC) of large scale structure cosmological probes, first in the case of angular power spectra. It necessita…
The Simons Observatory: Science goals and forecasts
The Simons Observatory Collaboration, Peter Ade, James Aguirre +247
The Simons Observatory (SO) is a new cosmic microwave background experiment being built on Cerro Toco in Chile, due to begin observations in the early 2020s. We describe the scient…
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…
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 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…
