Techniques for compact source extraction on CMB maps
R. B. Barreiro
The detection of compact sources embedded in a background is a very common problem in many fields of Astronomy. In these lecture notes we present a review of different techniques d…
Scalar statistics on the sphere: application to the CMB
C. Monteserin, R. B. Barreiro, J. L. Sanz +1
A method to compute several scalar quantities of Cosmic Microwave Background maps on the sphere is presented. We consider here four type of scalars: the Hessian matrix scalars, the…
Some comments on the note "Some comments on the paper 'Filter design for the detection of compact sources based on the Neyman-Pearson detector' by M. Lopez-Caniego et. al (2005, MNRAS 359, 993)" by R. Vio and P. Andreani (astroph/0509394)
M. Lopez-Caniego, D. Herranz, R. B. Barreiro +1
In this note we stress the necessity of a careful check of the arguments used by Vio & Andreani (2005) (VA hereinafter) to criticise the superior performance of the biparametric sc…
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…
Effect of component separation on the temperature distribution of the CMB
R. B. Barreiro, E. Martinez-Gonzalez, P. Vielva +1
We present a study of the effect of component separation on the recovered cosmic microwave background (CMB) temperature distribution, considering Gaussian and non-Gaussian input CM…
