Simulations of Foreground Effects for CMB Polarization
A. Kogut, G. Hinshaw
We use a simple model to investigate the effect of polarized Galactic foreground emission on the ability of planned CMB missions to detect and model CMB polarization. Emission from…
Looking for non-Gaussianity in the COBE-DMR data with spherical wavelets
R. B. Barreiro, M. P. Hobson, A. N. Lasenby +3
We present an analysis of the Gaussianity of the 4-year COBE-DMR data (in HEALPix pixelisation) based on spherical wavelets. The skewness, kurtosis and scale-scale correlation spec…
High-Latitude Galactic Emission in the COBE DMR Two-Year Sky Maps
A. Kogut, A. J. Banday, C. L. Bennett +3
We cross-correlate the COBE-DMR 2-year sky maps with spatial templates from long-wavelength radio surveys and the far-infrared COBE DIRBE maps. We place an upper limit on the spect…
On the RMS Anisotropy at 7 degrees and 10 degrees Observed in the COBE-DMR Two Year Sky Maps
A. J. Banday, K. M. Gorski, L. Tenorio +6
The frequency-independent RMS temperature fluctuations determined from the COBE-DMR two year sky maps are used to infer the parameter Q_{rms-PS}, which characterizes the normalizat…
CMB Maps at 0.5 Degree Resolution II: Unresolved Features
A. Kogut, G. Hinshaw, C. L. Bennett
High-contrast peaks in the cosmic microwave background (CMB) anisotropy can appear as unresolved sources to observers. We fit simulated CMB maps generated with a cold dark matter m…
CMB Maps at 0.5 degree Resolution I: Full-Sky Simulations and Basic Results
G. Hinshaw, C. L. Bennett, A. Kogut
We have simulated full-sky maps of the Cosmic Microwave Background (CMB) anisotropy expected from Cold Dark Matter (CDM) models at 0.5 and 1.0 degree angular resolution. Statistica…
