Foreground contamination is the fundamental hindrance to the cosmic microwave background (CMB) signals and its separation from it represents a fundamental question in Cosmology. On…
A theoretical framework for the detection of point-sources in Cosmic Microwave Background maps
R. Vio, P. Andreani
The detection of point-sources in microwave maps is a critical step in the analysis of the Cosmic Microwave Background (CMB) data. If not properly removed, these sources have adver…
European ALMA operations: the interaction with and support to the users

We present results of simulations performed with the Geant4 software code of the effects of Galactic Cosmic Ray impacts on the photoconductor arrays of the PACS instrument. This in…
Comments on the paper "The Mexican Hat Wavelet Family. Application to point source detection in CMB maps" by J. Gonzalez-Nuevo et al. (astro-ph/0604376)
Roberto Vio, Paola Andreani
The arguments presented by Gonzalez-Nuevo et. al (2006) in favour of the Mexican Hat Wavelet Family (MHWF) are critically discussed here. These authors allege the optimal propertie…
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)
R. Vio, P. Andreani
In this note we stress the necessity of a careful check of both the theoretical arguments and the numerical experiments used by Lopez-Caniego et al. (2005) to support the superior…
Digital Deblurring of CMB Maps II: Asymmetric Point Spread Function
R. Vio, J. G. Nagy, L. Tenorio +3
In this second paper in a series dedicated to developing efficient numerical techniques for the deblurring Cosmic Microwave Background (CMB) maps, we consider the case of asymmetri…

Averaged spectral energy distributions (SEDs) of active and starburst galaxies from the 12 micron sample in the Local Universe and Quasars, from an optically selected sample at a m…
Some Good Reasons to Use Matched Filters for the Detection of Point Sources in CMB Maps
Roberto Vio, Paola Andreani, Willelm Wamsteker
In this draft we comment on the results concerning the performances of matched filters, scale adaptive filters and Mexican hat wavelet that recently appeared in literature in the c…
