Probing inflation with CMB polarization

Daniel Baumann, +61 more
TL;DR: In this paper, the utility of precise cosmic microwave background (CMB) polarization measurements as probes of the physics of inflation was summarized, and the potential for using CMB measurements to differentiate various inflationary mechanisms was discussed.
Journal ArticleDOI

Cosmic variance and the measurement of the local Hubble parameter

TL;DR: It is shown that one would need a very rare fluctuation to fully explain the offset in the Hubble rates, and if this tension is further strengthened, a cosmology beyond the Standard Model may prove necessary.
Journal ArticleDOI

Testing the Void against Cosmological data: fitting CMB, BAO, SN and H0

TL;DR: In this paper, a large Gpc scale under-dense region (Void) is modeled by a Lema?tre-Tolman-Bondi metric that at large distances becomes a homogeneous FLRW metric.
Journal ArticleDOI

Testing the Copernican principle by constraining spatial homogeneity

TL;DR: In this article, the authors introduce a new measure to quantify violations of the Copernican principle, which is used to quantify radial inhomogeneity in a dark-energy dominated universe.
