Disentangling the gamma-ray emission of NGC1275 and that of the Perseus cluster
S. Colafrancesco, P. Marchegiani, P. Giommi
(Abridged). The gamma-ray emission from galaxy clusters hosting active galaxies is a complex combination of diffuse and point-like emission with different spectral and spatial prop…
Correlated Component Analysis for diffuse component separation with error estimation on simulated Planck polarization data
S. Ricciardi, A. Bonaldi, P. Natoli +6
We present a data analysis pipeline for CMB polarization experiments, running from multi-frequency maps to the power spectra. We focus mainly on component separation and, for the f…
New constraints on Parity Symmetry from a re-analysis of the WMAP-7 low resolution power spectra
A. Gruppuso, F. Finelli, P. Natoli +4
The Parity symmetry of the Cosmic Microwave Background (CMB) pattern as seen by WMAP 7 is tested jointly in temperature and polarization at large angular scale. A Quadratic Maximum…
Dark Matter in Modern Cosmology
S. Colafrancesco
The presence of Dark Matter (DM) is required in the universe regulated by the standard general relativistic theory of gravitation. The nature of DM is however still elusive to any…
Planck pre-launch status: the Planck-LFI programme
N. Mandolesi, M. Bersanelli, R. C. Butler +140
This paper provides an overview of the Low Frequency Instrument (LFI) programme within the ESA Planck mission. The LFI instrument has been developed to produce high precision maps…
X-ray spectral study of the hot gas in three Clusters of Galaxies
Y. G. Grange, E. Costantini, J. de Plaa +4
We study the physical properties of three clusters of galaxies, selected from a BeppoSAX Wide Field Camera (WFC) survey. These sources are identified as 1RXS J153934.7-833535, 1RXS…
