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…
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…
Statistical analysis of undetected point sources in cosmic microwave background maps
F. Argueso, J. L. Sanz, R. B. Barreiro +2
Cosmic microwave background (CMB) temperature anisotropies follow a Gaussian statistical distribution in the standard inflationary model, but there are non-Gaussian contributions d…
Polarized synchrotron emission
Carlo Burigana, Laura La Porta, Wolfgang Reich +4
Galactic synchrotron emission represents the most relevant foreground contamination in cosmic microwave background (CMB) anisotropy observations at angular scales $θ\gsim 1^\circ$…
Comparison of filters for the detection of point sources in Planck simulations
M. Lopez-Caniego, D. Herranz, J. Gonzalez-Nuevo +5
We study the detection of extragalactic point sources in two-dimensional flat simulations for all the frequencies of the forthcoming ESA's Planck mission. In this work we have used…
Predictions for high-frequency radio surveys of extragalactic sources
Gianfranco De Zotti, Roberto Ricci, Dino Mesa +4
We present detailed predictions of the contributions of the various source populations to the counts at frequencies of tens of GHz. New evolutionary models are worked out for flat-…
Predictions on high frequency polarization properties of extragalactic radio sources and implications for CMB polarization measurements
M. Tucci, E. Martinez-Gonzalez, L. Toffolatti +2
We present a method to simulate the polarization properties of extragalactic radio sources at microwave frequencies. Polarization measurements of nearly 2x10^6 sources at 1.4 GHz a…
