Journal ArticleDOI

Is the low-l microwave background cosmic?

TL;DR: It is shown that the quadrupole plane and the three octopole planes are far more aligned than previously thought (99.9% C.L.) with the direction of the cosmological dipole and with the equinoxes.
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.
Journal ArticleDOI

Multipole vectors - A New representation of the CMB sky and evidence for statistical anisotropy or non-Gaussianity at 2 <= l <= 8

TL;DR: In this paper, the authors proposed a novel representation of cosmic microwave anisotropy maps, where each multipole order is represented by unit vectors pointing in directions on the sky and an overall magnitude.
Journal ArticleDOI

Uncorrelated universe: Statistical anisotropy and the vanishing angular correlation function in WMAP years 1 3

TL;DR: The first year of the Wilkinson Microwave Anisotropy Probe (WMAP) observations exhibited statistically significant anomalies compared to the predictions of the standard inflationary big-bang model as discussed by the authors.
Journal ArticleDOI

On the large-angle anomalies of the microwave sky

TL;DR: In this paper, the authors apply the multipole vector framework to full-sky maps derived from the first-year Wilkinson Microwave Anisotropy Probe (WMAP) data.
