What is flat ΛCDM, and may we choose it?

Stefano Anselmi, Matthew F. Carney, John T. Giblin +5

The Universe is neither homogeneous nor isotropic, but it is close enough that we can reasonably approximate it as such on suitably large scales. The inflationary--Cold Dark Mat…

Hemispherical Variance Anomaly and Reionization Optical Depth

Marcio O'Dwyer, Craig J. Copi, Johanna M. Nagy +3

CMB full-sky temperature data show a hemispherical asymmetry in power nearly aligned with the Ecliptic. In real space, this anomaly can be quantified by the temperature variance in…

Linear Point and Sound Horizon as Purely Geometric standard rulers

Márcio O'Dwyer, Stefano Anselmi, Glenn D. Starkman +3

The Baryon Acoustic Oscillations feature (BAO) imprinted in the clustering correlation function is known to furnish us cosmic distance determinations that are independent of the co…

CMB-S4 and the Hemispherical Variance Anomaly

Marcio O'Dwyer, Craig J. Copi, Lloyd Knox +1

Cosmic Microwave Background (CMB) full-sky temperature data show a hemispherical asymmetry in power nearly aligned with the Ecliptic. In real space, this anomaly can be quantified…

The ISW effect and the lack of large-angle CMB temperature correlations

Craig J. Copi, Márcio O'Dwyer, Glenn D. Starkman

It is by now well established that the magnitude of the two-point angular-correlation function of the cosmic microwave background temperature anisotropies is anomalously low for an…
