Abstract:
The WMAP mission has mapped the full sky to determine the geometry,
content, and evolution of the universe. Full-sky maps are made in five
microwave frequency bands to separate the temperature anisotropy of
the cosmic microwave background (CMB) from foreground emission,
including diffuse Galactic emission and Galactic and extragalactic
point sources. We define masks that excise regions of high foreground
emission, so CMB analyses can be carried out with minimal foreground
contamination. We also present maps and spectra of the individual
emission components, leading to an improved understanding of Galactic
astrophysical processes.
Description:
The WMAP First Year Source Catalog is derived from the first year
skymaps produced by the Wilkinson Microwave Anisotropy Probe (WMAP)
satellite. Fluxes were measured in 5 bands between 23-94GHz. The
position uncertainty is 4-arcmin.
