Report

The impact of Galactic synchrotron emission on CMB anisotropy measurements. I. Angular power spectrum analysis of total intensity all-sky surveys

Autor: La Porta, L., Burigana, C., Reich, W., Reich, P.

Galactic foreground emission is a limiting factor for precise cosmic microwave background (CMB) anisotropy measurements. We perform an angular power spectrum analysis (APS) of all-sky total intensity maps at 408 MHz and 1420 MHz, which are dominated

Report

An angular power spectrum analysis of the DRAO 1.4 GHz polarization survey: implications for CMB observations

Autor: La Porta, L., Burigana, C., Reich, W., Reich, P.

The aim of the present analysis is to improve the knowledge of the statistical properties of the Galactic diffuse synchrotron emission, which constrains sensitive CMB anisotropy measurements. We have analysed the new DRAO 1.4 GHz polarization survey

Report

A statistical analysis of a Galactic all sky survey at 1.4 GHz

Autor: Burigana, C., La Porta, L., Reich, P., Reich, W.

Publikováno v: Astron.Nachr.327:491-492,2006

Radio surveys at frequencies of about 1 GHz allow to map the synchrotron emission in a frequency range where (except for very low Galactic latitudes or towards localized regions) it dominates over the other radio components. New all sky total intensi

Report

A Multifrequency Analysis of the Polarized Diffuse Galactic Radio Emission at Degree Scales

Autor: Burigana, C., La Porta, L.

Publikováno v: AIP Conf.Proc.609:54-59,2002

The polarized diffuse Galactic radio emission, mainly synchrotron emission, is expected to be one of the most relevant source of astrophysical contamination at low and moderate multipoles in cosmic microwave background polarization anisotropy experim

Report

Power spectrum of the polarized diffuse Galactic radio emission

Autor: Baccigalupi, C., Burigana, C., Perrotta, F., De Zotti, G., La Porta, L., Maino, D., Maris, M., Paladini, R.

Publikováno v: Astron. & Astrophys. 372, 8 (2001)

We have analyzed the available polarization surveys of the Galactic emission to estimate to what extent it may be a serious hindrance to forthcoming experiments aimed at detecting the polarized component of Cosmic Microwave Background (CMB) anisotrop
