Astrophysical components separation of COBE-DMR 4yr data with FastICA
We present an application of the fast Independent Component Analysis FastICA method to the COBE-DMR 4yr data. Although the signal-to-noise ratio in the COBE-DMR data is typically ∼ 1, the approach is able to extract the CMB signal with high confidence when working at high galactic latitudes. However, the foreground emission components have too low a S/N ratio to be reconstructed by this method ...
متن کاملCosmic Microwave Background Anisotropy in the Cobe Dmr 4-yr Sky Maps
The COBE satellite has provided the only comprehensive multi-frequency full-sky observations of the microwave sky available today. Assessment of the observations requires a detailed likelihood analysis to extract the maximum amount of information present in the noisy data. I present a specific method for estimating the CMB anisotropy power spectrum independent of any assumptions about the under...
متن کاملThe Trispectrum of the 4 Year Cobe Dmr Data
We propose an estimator for the trispectrum of a scalar random field on a sphere, discuss its geometrical and statistical properties, and outline its implementation. By estimating the trispectrum of the 4 yr COBE Differential Microwave Radiometer experiment data (in HEALPix pixelization), we find new evidence of a non-Gaussian signal associated with a known systematic effect. We find that by re...
متن کاملComparison of Cobe Dmr and Rosat All-sky Survey Data
Statistical comparisons of microwave maps in the GHz range and X-ray maps at around 1 keV are an interesting probe to constrain different astrophysical phenomena. Possible correlations on various angular scales and with different frequency (energy) dependences, although not expected at present day experimental sensitivity, could in principle be due to Galactic emission/absorption, the Sunyaev-Z...
متن کاملReappraising foreground contamination in the COBE-DMR data
With the advent of all-sky Hα surveys it is possible to determine a reliable free-free template of the diffuse interstellar medium (Dickinson, Davies & Davis 2003) which can be used in conjunction with the synchrotron and dust templates to correct CMB observations for diffuse Galactic foregrounds. We have used the COBE-DMR data at 31.5, 53 and 90 GHz and employed cross-correlation techniques to...
