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…
A novel multi-frequency technique for the detection of point sources in Cosmic Microwave Background maps
D. Herranz, M. Lopez-Caniego, J. L. Sanz +1
In this work we address the problem of simultaneous multi-frequency detection of extragalactic point sources in maps of the Cosmic Microwave Background. We apply a new linear filte…
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…
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…
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…
Wavelets on the sphere. Application to the detection problem
J. L. Sanz, D. Herranz, M. Lopez-Caniego +1
A new method is presented for the construction of a natural continuous wavelet transform on the sphere. It incorporates the analysis and synthesis with the same wavelet and the def…
