The spectrum of the Cosmic Microwave Background follows Planck's black body radiation formula and shows a remarkable constant temperature of T = 2.7. About 380 000 years after the Big Bang at a temperature of T = 3000 Kelvin in the matter dominated era the electrons combine with the protons and 4He and the photons move freely in the neutral universe. So the temperature and distribution of the photons give us information of the universe 380 000 years after the Big Bang. Information about earlier… Expand
Creation of Dirac neutrinos in a dense medium with a time-dependent effective potential
We consider Dirac neutrinos interacting with background fermions in the frame of the standard model. We demonstrate that a time-dependent effective potential is quite possible in a protoneutron starExpand
Electron capture in 163 Ho, overlap plus exchange corrections and neutrino mass
Holmium 163 offers perhaps the best chance to determine the neutrino mass by electron capture (EC). This contribution treats the EC in Holmium completely relativistic for the overlap and exchangeExpand
Sterile neutrino Dark Matter
We review sterile neutrinos as possible Dark Matter candidates. After a short summary on the role of neutrinos in cosmology and particle physics, we give a comprehensive overview of the currentExpand
Background due to secondary electron emission in the KATRIN experiment
KATRIN will determine the effective mass of the electron anti-neutrino with a sensitivity of 200 meV (90% C.L.) by scanning the tritium-beta-spectrum close to the endpoint energy with unprecedentedExpand


Search for the Cosmic Neutrino Background
One expects three Cosmic Backgrounds: (1) The Cosmic Microwave Background (CMB) originated 380000 years after the Big Bang (BB). (2) The Neutrino Background decoupled about one second after the BB,Expand
Beta Decaying Nuclei as a Probe of Cosmic Neutrino Background
relic neutrinos possessing very low energies. We focus on tritium ( 3 H) and rhenium ( 187 Re) beta radioactive isotopes to be used in KATRIN and MARE experiments dedicated to measurement of theExpand
Nine-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Final Maps and Results
We present the final nine-year maps and basic results from the Wilkinson Microwave Anisotropy Probe (WMAP) mission. The full nine-year analysis of the time-ordered data provides updatedExpand
