Astro-ph communication: Simulations of the WMAP Internal Linear Combination sky map
H. K. Eriksen, A. J. Banday, K. M. Gorski +1
Following this astro-ph communication, we release a set of 10,000 WMAP ILC simulations, produced as described by Eriksen et al. (2004). We strongly encourage that an analysis of th…
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…
The HEALPix Primer
Krzysztof M. Gorski, Benjamin D. Wandelt, Frode K. Hansen +2
HEALPix is a Hierarchical, Equal Area, and iso-Latitude Pixelisation of the sphere designed to support efficiently - local operations on the pixel set, - a hierarchical tree struct…
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…
