# Assessing the effects of foregrounds and sky removal in WMAP

@article{Slosar2004AssessingTE, title={Assessing the effects of foregrounds and sky removal in WMAP}, author={An{\vz}e Slosar and Uros Seljak}, journal={Physical Review D}, year={2004}, volume={70}, pages={083002} }

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 effects of foreground contamination, which require elimination of some fraction of the data, have not been fully investigated due to the complexity in the analysis. Here we develop a general formalism of how to incorporate these effects into any analysis of this type. Our approach is to compute the…

### COSMOLOGICAL IMPLICATIONS OF THE CMB LARGE-SCALE STRUCTURE

- Physics
- 2012

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…

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

- Environmental Science
- 2004

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…

### Effect of foregrounds on the cosmic microwave background radiation multipole alignment

- Physics
- 2011

We analyse the effect of foregrounds on the observed alignment of the cosmic microwave background radiation (CMBR) quadrupole and octopole. The alignment between these multipoles is studied by using…

### Cosmological parameters and the WMAP data revisited

- Physics
- 2004

Several recent papers have made claims about the detection of an asymmetric distribution of large-scale power in the cosmic microwave background (CMB) anisotropy as measured by the WMAP satellite. In…

### On preferred axes in WMAP cosmic microwave background data after subtraction of the integrated Sachs-Wolfe effect

- Physics
- 2013

There is currently a debate over the existence of claimed statistical anomalies in the cosmic microwave background (CMB), recently confirmed in Planck data. Recent work has focussed on methods for…

### Constraints on mode couplings and modulation of the CMB with WMAP data

- Physics
- 2005

We investigate a possible asymmetry in the statistical properties of the cosmic microwave background temperature field and to do so we construct an estimator aiming at detecting a dipolar modulation.…

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

- Physics
- 2014

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…

### Bias in low-multipole cosmic microwave background reconstructions

- Mathematics
- 2011

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…

### The N-Point Correlation Functions of the First-Year Wilkinson Microwave Anisotropy Probe Sky Maps

- Physics
- 2005

We compute the two-, three- and four-point correlation functions from the Wilkinson Microwave Anisotropy Probe (WMAP) first-year data and compare these with a Monte Carlo ensemble of 5000…

### Covariance of CMB anomalies

- PhysicsPhysical Review D
- 2018

Several unexpected features are observed at large angular scales in the CMB temperature anisotropy measurements by both WMAP and Planck. These include the lack of both variance and correlation,…
