The CMB Power Spectrum from the Background Emission Anisotropy Scanning Telescope (BEAST) Experiment
Ian J. O'Dwyer, Marco Bersanelli, Jeffrey Childers +19
The Background Emission Anisotropy Scanning Telescope (BEAST) is a 2.2m off-axis telescope with an 8 element mixed Q (38-45GHz) and Ka (26-36GHz) band focal plane, designed for bal…
Signature of HDM clustering at Planck angular scales
L. A. Popa, C. Burigana, N. Mandolesi
We present the CMB anisotropy induced by the non-linear perturbations in the massive neutrino density associated to the non-linear gravitational clustering. We show that the non-li…
Non-linear evolution of the cosmological background density field as diagnostic of the cosmological reionization
L. A. Popa, C. Burigana, N. Mandolesi
We present constraints on the cosmological and reionization parameters based on the cumulative mass function of the Ly-alpha systems. We find that the analysis of the cumulative ma…
High Performances Corrugated Feed Horns for Space Applications at Millimetre Wavelengths
F. Villa, M. Sandri, N. Mandolesi +11
We report on the design, fabrication and testing of a set of high performance corrugated feed horns at 30 GHz, 70 GHz and 100 GHz, built as advanced prototypes for the Low Frequenc…
Advanced pseudo-correlation radiometers for the Planck-LFI instrument
A. Mennella, M. Bersanelli, R. C. Butler +34
The LFI (Low Frequency Instrument) on board the ESA Planck satellite is constituted by an array of radiometric detectors actively cooled at 20 K in the 30-70 GHz frequency range in…
Trade-off between angular resolution and straylight contamination in CMB anisotropy experiments. I. Pattern simulations
M. Sandri, F. Villa, R. Nesti +3
The study of Cosmic Microwave Background (CMB) anisotropies represents one of the most powerful Cosmological tools. After the great success of the two NASA's satellite missions COB…
