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…
Matrix Filters for the Detection of Extragalactic Point Sources in Cosmic Microwave Background Images
D. Herranz, J. L. Sanz
In this paper we introduce a new linear filtering technique, the so-called matrix filters, that maximizes the signal-to-interference ratio of compact sources of unknown intensity e…
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…
Observing high redshift galaxy clusters through lensing of the Ostriker-Vishniac effect
J. M. Diego, D. Herranz
In this paper we study the possibility of detecting lensing signals in high-resolution and high-sensitivity CMB experiments. At scales below 1 arcmin, the CMB background is dominat…
