Planck 2013 results . XXVIII . The Planck Catalogue of Compact Sources
The Planck Catalogue of Compact Sources (PCCS) is the catalogue of sources detected in the first 15 months of Planck operations, the “nominal” mission. It consists of nine single-frequency catalogues of compact sources, both Galactic and extragalactic, detected over the entire sky. The PCCS covers the frequency range 30–857 GHz with higher sensitivity (it is 90 % complete at 180 mJy in the best...
متن کاملThe Fokker-Planck equation
In 1984, H. Risken authored a book (H. Risken, The Fokker-Planck Equation: Methods of Solution, Applications, Springer-Verlag, Berlin, New York) discussing the Fokker-Planck equation for one variable, several variables, methods of solution and its applications, especially dealing with laser statistics. There has been a considerable progress on the topic as well as the topic has received greater...
متن کاملThe Fokker-Planck Equation
Stochastic differential equations (SDE) are used to model many situations including population dynamics, protein kinetics, turbulence, finance, and engineering [5, 6, 1]. Knowing the solution of the SDE in question leads to interesting analysis of the trajectories. Most SDE are unsolvable analytically and other methods must be used to analyze properties of the stochastic process. From the SDE, ...
متن کاملThe Planck mission François
These lecture notes discuss some aspects of the Planck1 mission, whose prime objective was a very accurate measurement of the temperature anisotropies of the Cosmic Microwave Background (CMB). We announced our findings a few months ago, on March 21st , 2013. I describe some of the relevant steps we took to obtain these results, sketching the measurement process, how we processed the data to obt...
متن کاملNeutrino Masses from Planck to Planck
Koide parameters for both neutrino and mirror neutrino triplets are examined in light of the CMB mirror neutrino correspondence. This note is just to record slightly improved rest mass predictions for the neutrinos. In the 1980s, Koide predicted the τ lepton rest mass using the simple relation √ memμ + √ mμmτ + √ mτme me + mμ + mτ = 1 4 (1) involving the more accurately known electron and muon ...
