witam cosmo-torun,
Andrzej Kus mi prosił zrobić seminarium poniedziałek 9.10.2006.
Jeśli ktoś chce sugerować poprawki, proszę mów. Abstrakt jest raczej długi, ale jest trudny zrobić krótkiejszy dla osoby nie znając temat...
Oczywiście, będę też iść trochę na wyniki WMAP itd, ale nie widzę, że muszę to mówić w abstrakcie.
pozdr boud
Title
2006 Nobel prize: Cosmological black body and density perturbations
Abstract
The standard hot big bang model became widely accepted as a serious model in 1965 after the discovery of the 3 Kelvin primordial background radiation (CMB), but it was still regarded sceptically by many astronomers. During the 1980s and early 1990s, the model's prediction that the background radiation should have a nearly perfect Planckian black body spectrum was only weakly tested. The other untested prediction of the model was that the Universe is not perfectly uniform, it needed density perturbations which could gravitationally collapse to form clusters of galaxies and galaxies and stars. The COBE satellite, coordinated by Smoot, Mather and Wilkinson, revealed that the CMB black body was more perfect than any black body created artificially in Earth based laboratories. Moreover, in its map of the CMB, it detected 0.001% fluctuations in the temperature - revealing the density perturbations necessary to form galaxies. These results spectacularly confirmed two of the basic physical predictions of the hot big bang model.
