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…
Offset balancing in pseudo-correlation radiometers for CMB measurements
Aniello Mennella, Marco Bersanelli, Michael Seiffert +4
Radiometeric CMB measurements need to be highly stable and this stability is best obtained with differential receivers. The residual 1/f noise in the differential output is strongl…
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…
A Map of the Cosmic Microwave Background from the BEAST Experiment
Peter R. Meinhold, Marco Bersanelli, Jeffrey Childers +24
We present the first sky maps from the BEAST (Background Emission Anisotropy Scanning Telescope) experiment. BEAST consists of a 2.2 meter off axis Gregorian telescope fed by a cry…
