Angular fluctuations in the cosmological microwave background in a universe with a cosmological constant
Abstract
The author investigates the temperature fluctuations of the cosmological background in a universe with a positive cosmological constant. Because of the geometry of light rays the angular δT/T can be quite different than in the standard model. As a result, the adiabatic scenario may be consistent with the observed upper limit on the microwave background even if Ω0h2 ⪉ 0.1.
