CMB-S4 Science Book, First Edition
- K. Abazajian, P. Adshead, W. L. K. Wu
- Physics
- 9 October 2016
This book lays out the scientific goals to be addressed by the next-generation ground-based cosmic microwave background experiment, CMB-S4, envisioned to consist of dedicated telescopes at the South…
CMB-S4 Science Case, Reference Design, and Project Plan
- K. Abazajian, G. Addison, A. Zonca
- Physics
- 9 July 2019
We present the science case, reference design, and project plan for the Stage-4 ground-based cosmic microwave background experiment CMB-S4.
“In-in” formalism and cosmological perturbations
- P. Adshead, R. Easther, Eugene A Lim
- Physics
- 27 April 2009
We describe an efficient scheme for evaluating higher order contributions to primordial cosmological perturbations using the ``in-in'' formalism, which is the basis of modern calculations of…
CMBPol Mission Concept Study Probing Ination with CMB Polarization
- D. Baumann, M. Jackson, M. Zaldarriaga
- Physics
- 24 November 2008
We summarize the utility of precise cosmic microwave background (CMB) polarization measurements as probes of the physics of ination. We focus on the prospects for using CMB measurements

Perturbations in Chromo-Natural Inflation
- P. Adshead, E. Martinec, M. Wyman
- Physics
- 13 May 2013
A bstractChromo-Natural Inflation is the first worked example of a model of inflation in which slow-roll inflation is achieved by “magnetic drift” as opposed to Hubble friction. In this work, we give…
Non-Gaussianity from Step Features in the Inflationary Potential
- P. Adshead, C. Dvorkin, Wayne Hu, Eugene A Lim
- Physics
- 13 October 2011
We provide analytic solutions for the power spectrum and bispectrum of curvature fluctuations produced by a step feature in the inflaton potential, valid in the limit that the step is short and…
Probing inflation with CMB polarization
- D. Baumann, M. Jackson, M. Zaldarriaga
- Physics
- 23 June 2008
We summarize the utility of precise cosmic microwave background (CMB) polarization measurements as probes of the physics of inflation. We focus on the prospects for using CMB measurements to…
Gauge fields and inflation: Chiral gravitational waves, fluctuations, and the Lyth bound
- P. Adshead, E. Martinec, M. Wyman
- Physics
- 11 January 2013
Models of inflation involving non-Abelian gauge field backgrounds can produce gravitational waves at an observable level with a preferred handedness. This asymmetry comes about because the…
Reionization and the large-scale 21-cm cosmic microwave background cross-correlation
- P. Adshead, S. Furlanetto
- Physics
- 21 June 2007
Of the many probes of reionization, the 21-cm line and the cosmic microwave background (CMB) are among the most effective. We examine how the cross-correlation of the 21-cm brightness and the CMB…
