CMB-S4 Science Book, First Edition

TL;DR: The CMB-S4 project as mentioned in this paper is a ground-based cosmic microwave background (CMB) experiment with superconducting cameras, which will be used for the search for the B-mode polarization signature of primordial gravitational waves and the determination of the number and masses of neutrinos.
Journal ArticleDOI

Dynamical dark energy in light of the latest observations

TL;DR: In this article, the authors investigated whether these tensions can be interpreted as evidence for a non-constant dynamical dark energy and found that the tensions are relieved by an evolving dark energy model preferred at a 3.5σ significance level based on the improvement in the fit alone.

Kevork N. Abazajian, +224 more
TL;DR: In this article, the authors present the science case, reference design, and project plan for the Stage-4 ground-based cosmic microwave background experiment CMB-S4, as well as the experimental data.
Journal ArticleDOI

Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies

Elcio Abdalla, +202 more
TL;DR: In this paper , the authors focus on the 5.0σ tension between the Planck CMB estimate of the Hubble constant H0 and the SH0ES collaboration measurements and discuss the importance of trying to fit a full array of data with a single model.
