We investigate anomalies reported in the Cosmic Microwave Background maps from the Wilkinson Microwave Anisotropy Probe (WMAP) satellite on very large angular scales and discuss possible interpretations. Three independent anomalies involve the quadrupole and octopole: 1. The cosmic quadrupole on its own is anomalous at the 1-in-20 level by being low (the cut-sky quadrupole measured by the WMAP team is more strikingly low, apparently due to a coincidence in the orientation of our Galaxy of no… 
COSMOLOGICAL IMPLICATIONS OF THE CMB LARGE-SCALE STRUCTURE
The Wilkinson Microwave Anisotropy Probe (WMAP) and Planck may have uncovered several anomalies in the full cosmic microwave background (CMB) sky that could indicate possible new physics driving the
Cosmic Microwave Background large-scale directional anomalies as seen by Planck and WMAP
It has been found that large-scale anisotropies in the Cosmic Microwave Background are anomalous with respect to the predictions of the standard model of cosmology. We focused on the low multipole
Can a primordial magnetic field originate large-scale anomalies in WMAP data?
Several accurate analyses of the cosmic microwave background (CMB) temperature maps from the Wilkinson Microwave Anisotropy Probe (WMAP) have revealed a set of anomalous results, at large angular
On the cosmic microwave background large-scale angular correlations
Aims. We study the large-scale angular correlation signatures of the cosmic microwave background (CMB) temperature fluctuations from WMAP data in several spherical cap regions of the celestial
The cosmic microwave background quadrupole in a polarized light
The low quadrupole of the cosmic microwave background (CMB), measured by the Cosmic Background Explorer (COBE) and confirmed by the Wilkinson Microwave Anisotropy Probe (WMAP), has generated much
The actual Rees-Sciama effect from the local universe
Observations of the Cosmic Microwave Background (CMB) have revealed an unexpected quadrupole-octopole alignment along a preferred axis pointing toward the Virgo cluster. We here investigate whether
Evidence of Vorticity and Shear at Large Angular Scales in the WMAP Data: A Violation of Cosmological Isotropy?
Motivated by the large-scale asymmetry observed in the cosmic microwave background sky, we consider a specific class of anisotropic cosmological models—Bianchi type VIIh—and compare them to the WMAP
A low cosmic microwave background variance in the Wilkinson Microwave Anisotropy Probe data
We have estimated the cosmic microwave background (CMB) variance from the three-year Wilkinson Microwave Anisotropy Probe (WMAP) data, finding a value which is significantly lower than the one
Can residuals of the solar system foreground explain low multipole anomalies of the CMB
The low multipole anomalies of the Cosmic Microwave Background has received much attention during the last few years. It is still not ascertained whether these anomalies are indeed primordial or the

Suppressing the lower multipoles in the CMB anisotropies
The Cosmic Microwave Background (CMB) anisotropy power on the largest angular scales observed both by WMAP and COBE DMR appears to be lower than the one predicted by the standard model of cosmology
Two‐point anisotropies in WMAP and the cosmic quadrupole

Getting around cosmic variance
Cosmic microwave background (CMB) anisotropies probe the primordial density field at the edge of the observable Universe. There is a limiting precision (“cosmic variance”) with which anisotropies can
Can cosmic shear shed light on low cosmic microwave background multipoles?
TLDR
The lowest multipole moments of the cosmic microwave background (CMB) are smaller than expected for a scale-invariant power spectrum, and a cutoff in the primordial power spectrum below a comoving scale of k(c) approximately equal to 5.0 x 10(-4) Mpc(-1).

TLDR
A simple geometrical model of a finite space—the Poincaré dodecahedral space—which accounts for WMAP's observations with no fine-tuning required is presented, and the model also predicts temperature correlations in matching circles on the sky.

TLDR
Large-scale cosmic microwave background temperature fluctuations are calculated for a universe with the topology of a 3-torus and it is found that a topologically ``small'' universe is no longer an interesting cosmological model.
