Blind and non-blind source detection in WMAP 5-year maps
M. Massardi, M. López-Caniego, J. González-Nuevo +3
We have analyzed the efficiency in source detection and flux density estimation of blind and non-blind detection techniques exploiting the MHW2 filter applied to the Wilkinson Micr…
Component separation methods for the Planck mission
S. M. Leach, J. -F. Cardoso, C. Baccigalupi +27
The Planck satellite will map the full sky at nine frequencies from 30 to 857 GHz. The CMB intensity and polarization that are its prime targets are contaminated by foreground emis…
Observability of the virialization phase of spheroidal galaxies with radio arrays
M. Massardi, A. Lapi, G. De Zotti +2
In the standard galaxy formation scenario plasma clouds with a high thermal energy content must exist at high redshifts since the proto-galactic gas is shock heated to the virial t…
Statistical properties of extragalactic sources in the New Extragalactic WMAP Point Source (NEWPS) catalogue
J. González-Nuevo, M. Massardi, F. Argüeso +5
We present results on spectral index distributions, number counts, redshift distribution and other general statistical properties of extragalactic point sources in the NEWPS5 sampl…
The Australia Telescope 20 GHz (AT20G) Survey: The Bright Source Sample
Marcella Massardi, Ronald D. Ekers, Tara Murphy +14
The Australia Telescope 20 GHz (AT20G) Survey is a blind survey of the whole Southern sky at 20 GHz (with follow-up observations at 4.8 and 8.6 GHz) carried out with the Australia…
Non-blind catalogue of extragalactic point sources from the Wilkinson Microwave Anisotropy Probe (WMAP) first 3--year survey data
M. Lopez-Caniego, J. Gonzalez-Nuevo, D. Herranz +5
We have used the MHW2 filter to obtain estimates of the flux densities at the WMAP frequencies of a complete sample of 2491 sources, mostly brighter than 500 mJy at 5 GHz, distribu…
