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…
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…
Filter design for the detection of compact sources based on the Neyman-Pearson detector
M. Lopez-Caniego, D. Herranz, R. B. Barreiro +1
This paper considers the problem of compact source detection on a Gaussian background in 1D. Two aspects of this problem are considered: the design of the detector and the filterin…
A Bayesian approach to filter design: detection of compact sources
M. Lopez-Caniego, D. Herranz, R. B. Barreiro +1
We consider filters for the detection and extraction of compact sources on a background. We make a one-dimensional treatment (though a generalization to two or more dimensions is p…
The estimation of the SZ effects with unbiased multifilters
D. Herranz, J. L. Sanz, R. B. Barreiro +1
In this work we study the performance of linear multifilters for the estimation of the amplitudes of the thermal and kinematic Sunyaev-Zel'dovich effects. We show that when both ef…
