Making Maps from Planck LFI 30GHz Data with Asymmetric Beams and Cooler Noise
M. A. J. Ashdown, C. Baccigalupi, J. G. Bartlett +21
The Planck satellite will observe the full sky at nine frequencies from 30 to 857 GHz. The goal of this paper is to examine the effects of four realistic instrument systematics in…
The Planck Low Frequency Instrument
N. Mandolesi, C. Burigana, R. C. Butler +14
Planck is the third generation of mm-wave instruments designed for space observations of the cosmic microwave background (CMB) anisotropies within the new Cosmic Vision 2020 ESA Sc…
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…
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…
Planck Low Frequency Instrument: Beam Patterns
M. Sandri, M. Bersanelli, C. Burigana +8
The Low Frequency Instrument on board the ESA Planck satellite is coupled to the Planck 1.5 meter off-axis dual reflector telescope by an array of 27 corrugated feed horns operatin…
Advanced simulation techniques for straylight prediction of high performance mm-wave reflecting telescope
M. Sandri, F. Villa, M. Bersanelli +3
The prediction of the antenna radiation pattern can be extremely complex for antenna system composed of several reflector surfaces. Typically, at mm-wavelengths, telescopes are com…
PLANCK/LFI: an Advanced Multi-beam High Performance mm-wave Optics for Space Applications
F. Villa, M. Sandri, M. Bersanelli +5
The Low Frequency Instrument (LFI) is one of the two instruments onboard the ESA PLANCK satellite foreseen to be launched in 2007. The LFI will image the Cosmic Microwave Backgroun…
Trade-off between angular resolution and straylight contamination in CMB anisotropy experiments. II. Straylight evaluation
C. Burigana, M. Sandri, F. Villa +5
Satellite CMB anisotropy missions and new generation of balloon-borne and ground experiments, make use of complex multi-frequency instruments at the focus of a meter class telescop…
Sources Variability With Planck LFI
L. Terenzi, M. Bersanelli, C. Burigana +8
Planck LFI (Low Frequency Instrument) will produce a complete survey of the sky at millimeter wavelengths. Data stream analysis will provide the possibility to reveal unexpected mi…
The Planck Telescope
F. Villa, M. Bersanelli, C. Burigana +7
In this paper we present an overview of the Telescope designed for ESA's mission dedicated to map the Cosmic Microwave Background Anisotropies and Polarization. Two instruments, LF…
The Planck Low Frequency Instrument
N. Mandolesi, M. Bersanelli, C. Burigana +1
The Low Frequency Instrument (LFI) of the "Planck Surveyor" ESA mission will perform high-resolution imaging of the Cosmic Microwave Background anisotropies at four frequencies in…
