Journal ArticleDOI
Concerning the connection between the Cℓ power spectrum of the cosmic microwave background and the Γm Fourier spectrum of rings on the sky
R. Ansari,S. Bargot,A. Bourrachot,F. Couchot,J. Haissinski,Sophie Henrot-Versille,G. Le Meur,O. Perdereau,M. Piat,Stéphane Plaszczynski,F. Touze +10 more
TL;DR: In this paper, the scaling law of the m m cosmic microwave background Fourier spectrum on rings was studied and a scaling law was proposed to recover the C power spectrum at the 1 per cent level for colatitudes > 80 •.
Journal ArticleDOI
About the connection between the $C_{\ell}$ power spectrum of the Cosmic Microwave Background and the $\Gamma_{m}$ Fourier spectrum of rings on the sky

TL;DR: In this paper, the scaling law of the CMB Fourier spectrum on rings was studied and a scaling law was proposed to recover the spectrum at the 1% level for colatitudes ≥ 80^\circ$ degrees.

TL;DR: The first phase of the EROS search for gravitational microlensing of stars in the Magellanic Clouds by unseen deflectors (machos: MAssive Compact Halo Objects) was reported in this paper.
Proceedings ArticleDOI
A new pulse shape description for $\alpha$ particle pulses in a highly-sensitive sub-Kelvin bolometer
TL;DR: In this paper, the authors compared the typical fitting algorithm (a mathematical model) with a second method of pulse interpretation by convolving the detector's thermal response function with a starting profile of thermalised athermal phonons, taking into account the effects of heat propagation.

TL;DR: In this article, the performance of the Planck instruments in space is enabled by their low operating temperatures, 20K for LFI and 0.1K for HFI, achieved through a combination of passive radiative cooling and three active mechanical coolers.
