New Horizons in Cosmology with Spectral Distortions of the Cosmic Microwave Background
J. Chluba, M. H. Abitbol, N. Aghanim +27
Voyage 2050 White Paper highlighting the unique science opportunities using spectral distortions of the cosmic microwave background (CMB). CMB spectral distortions probe many proce…
A Space Mission to Map the Entire Observable Universe using the CMB as a Backlight
Kaustuv Basu, Mathieu Remazeilles, Jean-Baptiste Melin +22
This Science White Paper, prepared in response to the ESA Voyage 2050 call for long-term mission planning, aims to describe the various science possibilities that can be realized w…
Microwave Spectro-Polarimetry of Matter and Radiation across Space and Time
Jacques Delabrouille, Maximilian H. Abitbol, Nabila Aghanim +77
This paper discusses the science case for a sensitive spectro-polarimetric survey of the microwave sky. Such a survey would provide a tomographic and dynamic census of the three-di…
PICO: Probe of Inflation and Cosmic Origins
S. Hanany, M. Alvarez, E. Artis +79
The Probe of Inflation and Cosmic Origins (PICO) is a proposed probe-scale space mission consisting of an imaging polarimeter operating in frequency bands between 20 and 800 GHz. W…
CMB-S4 Decadal Survey APC White Paper
Kevork Abazajian, Graeme Addison, Peter Adshead +222
We provide an overview of the science case, instrument configuration and project plan for the next-generation ground-based cosmic microwave background experiment CMB-S4, for consid…
The Simons Observatory: Astro2020 Decadal Project Whitepaper
The Simons Observatory Collaboration, Maximilian H. Abitbol, Shunsuke Adachi +280
The Simons Observatory (SO) is a ground-based cosmic microwave background (CMB) experiment sited on Cerro Toco in the Atacama Desert in Chile that promises to provide breakthrough…
CMB-S4 Science Case, Reference Design, and Project Plan
Kevork Abazajian, Graeme Addison, Peter Adshead +222
We present the science case, reference design, and project plan for the Stage-4 ground-based cosmic microwave background experiment CMB-S4.
Planck 2018 results. V. CMB power spectra and likelihoods
Planck Collaboration, N. Aghanim, Y. Akrami +165
This paper describes the 2018 Planck CMB likelihoods, following a hybrid approach similar to the 2015 one, with different approximations at low and high multipoles, and implementin…
Mapping the relativistic electron gas temperature across the sky
Mathieu Remazeilles, Jens Chluba
With increasing sensitivity, angular resolution, and frequency coverage, future cosmic microwave background (CMB) experiments like PICO will allow us to access new information abou…
Planck 2018 results. VII. Isotropy and Statistics of the CMB
Planck Collaboration, Y. Akrami, M. Ashdown +147
Analysis of the Planck 2018 data set indicates that the statistical properties of the cosmic microwave background (CMB) temperature anisotropies are in excellent agreement with pre…
Planck 2018 results. IX. Constraints on primordial non-Gaussianity
Planck Collaboration, Y. Akrami, F. Arroja +157
We analyse the Planck full-mission cosmic microwave background (CMB) temperature and E-mode polarization maps to obtain constraints on primordial non-Gaussianity (NG). We compare e…
Spectral Distortions of the CMB as a Probe of Inflation, Recombination, Structure Formation and Particle Physics
J. Chluba, A. Kogut, S. P. Patil +98
Following the pioneering observations with COBE in the early 1990s, studies of the cosmic microwave background (CMB) have focused on temperature and polarization anisotropies. CMB…
"SZ spectroscopy" in the coming decade: Galaxy cluster cosmology and astrophysics in the submillimeter
Kaustuv Basu, Jens Erler, Jens Chluba +30
Sunyaev-Zeldovich (SZ) effects were first proposed in the 1970s as tools to identify the X-ray emitting hot gas inside massive clusters of galaxies and obtain their velocities rela…
PICO: Probe of Inflation and Cosmic Origins
Shaul Hanany, Marcelo Alvarez, Emmanuel Artis +79
The Probe of Inflation and Cosmic Origins (PICO) is an imaging polarimeter that will scan the sky for 5 years in 21 frequency bands spread between 21 and 799 GHz. It will produce f…
