Cosmological constraints on the amplitude of relic gravitational waves

Abstract: Проаналiзовано розвиток амплiтуди релiктових ґравiтацiйних хвиль (РҐХ), зґенерованих у ранньому Всесвiтi. Наведено аналiтичну апроксимацiю кутового спектра потужности флюктуацiй температури релiктового електромагнетного випромiнювання (РЕВ), зумовлених такими ґравiтацiйними хвилями через ефект Сакса-Вольфа. Отримано оцiнку найбiльш iмовiрного значення цiєї амплiтуди на основi даних спостережень анiзотропiї температури релiктового електромагнетного випромiнювання, одержаних в експериментах COBE, WMAP i BOOMERan… Show more

“…Assuming no correlation between the values of power in adjacent bins we get χ 2 = 37.8 for 33 degrees of freedom. Also for comparison we have plotted by dotted line the spectrum of ΛCDM model with values of parameters given as best-fit to the data of first-year WMAP observations and large-scale structure of the Universe [1,2], χ 2 = 68.2 for this spectrum.…”

“…Solid line denotes the spectrum in best-fit ΛCDM model according to the data of [35] (χ 2 = 37.8). The dotted line denotes the spectrum for ΛCDM model which is the best-fit to 1-year WMAP data and large-scale structure observables [1,2] (χ 2 = 68.2). The dashed line depicts the spectrum of ΛCDM3 model with parameters found further in this paper (χ 2 = 37.2).…”
