The large-angle, low-multipole cosmic microwave background (CMB) provides a unique view of the largest angular scales in the Universe. Study of these scales is hampered by the facts that we have only one Universe to observe, only a few independent samples of the underlying statistical distribution of these modes, and an incomplete sky to observe due to the interposing Galaxy. Techniques for reconstructing a full sky from partial-sky data are well known and have been applied to the large angular… 

A survey of lens spaces and large‐scale cosmic microwave background anisotropy

The cosmic microwave background (CMB) anisotropy possesses the remarkable property that its power is strongly suppressed on large angular scales. This observational fact can naturally be explained by

Lack of large-angle TT correlations persists in WMAP and Planck

The lack of large-angle correlations in the observed microwave backgroundtemperature fluctuations persists in the final-year maps from WMAP and thefirst cosmological data release from Planck. We find

Planck CMB anomalies: astrophysical and cosmological secondary effects and the curse of masking

Large-scale anomalies have been reported in CMB data with both WMAP and Planck data. These could be due to foreground residuals and or systematic effects, though their confirmation with Planck data

Cosmic topology of polyhedral double-action manifolds

A special class of non-trivial topologies of the spherical space is investigated with respect to their cosmic microwave background (CMB) anisotropies. The observed correlations of the anisotropies on

Calibration errors unleashed: effects on cosmological parameters and requirements for large-scale structure surveys

Imperfect photometric calibration of galaxy surveys due to either astrophysical or instrumental effects leads to biases in measuring galaxy clustering and in the resulting cosmological parameter



Low‐order multipole maps of cosmic microwave background anisotropy derived from WMAP

Recent analyses of the Wilkinson Microwave Anisotropy Probe (WMAP) data have suggested that the low-order multipoles of the cosmic microwave background (CMB) anisotropy distribution show

Large-angle correlations in the cosmic microwave background

It has been argued recently by Copi et al. 2009 that the lack of large angular correlations of the CMB temperature field provides strong evidence against the standard, statistically isotropic,

The cut-sky cosmic microwave background is not anomalous

The observed angular correlation function of the cosmic microwave background has previously been reported to be anomalous, particularly when measured in regions of the sky uncontaminated by Galactic

Assessing the effects of foregrounds and sky removal in WMAP

Many recent analyses have indicated that large scale Wilkinson Microwave Anisotropy Probe (WMAP) data display anomalies that appear inconsistent with the standard cosmological paradigm. However, the

Significance of the largest scale CMB fluctuations in WMAP

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

The multipole vectors of the Wilkinson Microwave Anisotropy Probe, and their frames and invariants

We investigate the statistical isotropy (SI) and Gaussianity of the cosmic microwave background fluctuations, using a set of multipole vector functions capable of separating these two issues. In

Systematic distortion in cosmic microwave background maps

To minimize instrumentally the induced systematic errors, cosmic microwave background (CMB) anisotropy experiments measure temperature differences across the sky using pairs of horn antennas,

Four-Year COBE DMR Cosmic Microwave Background Observations: Maps and Basic Results

In this Letter we present a summary of the spatial properties of the cosmic microwave background radiation based on the full 4 yr of COBE Differential Microwave Radiometer (DMR) observations, with

Fast estimation of polarization power spectra using correlation functions

We present a fast method for estimating the cosmic microwave background polarization power spectra using unbiased estimates of heuristically weighted correlation functions. This extends the O(N 3/2
