Calibration and First light of the Diabolo photometer at the Millimetre and Infrared Testa Grigia Observatory
A. Benoit, F. Zagury, N. Coron +26
We have designed and built a large-throughput dual channel photometer, Diabolo. This photometer is dedicated to the observation of millimetre continuum diffuse sources, and in part…
Complex Brjuno functions
S. Marmi, P. Moussa, J. -C. Yoccoz
The Brjuno function arises naturally in the study of one--dimensional analytic small divisors problems. It belongs to and it is stable under Hölder pertu…
A measurement of Omega from the North American test flight of BOOMERANG
A. Melchiorri, P. A. R. Ade, P. de Bernardis +22
We use the angular power spectrum of the Cosmic Microwave Background, measured during the North American test flight of the BOOMERANG experiment, to constrain the geometry of the u…
Measurement of a Peak in the Cosmic Microwave Background Power Spectrum from the North American test flight of BOOMERANG
P. D. Mauskopf, P. A. R. Ade, P. de Bernardis +31
We describe a measurement of the angular power spectrum of anisotropies in the Cosmic Microwave Background (CMB) from 0.3 degrees to ~10 degrees from the North American test flight…
Stokes formula and density perturbances for driven tracer diffusion in an adsorbed monolayer
O. Benichou, A. M. Cazabat, J. De Coninck +2
We study the intrinsic friction of monolayers adsorbed on solid surfaces from a gas phase or vapor. Within the framework of the Langmuir model of delocalized adsorption, we calcula…
First Results from Viper: Detection of Small-Scale Anisotropy at 40 GHZ
J. B. Peterson, G. S. Griffin, M. G. Newcomb +7
Results of a search for small-scale anisotropy in the cosmic microwave background (CMB) are presented. Observations were made at the South Pole using the Viper telescope, with a .2…
