Quintessence Model

A particular kind of quintessence is considered with equation of motion pQ/ρQ = -1, corresponding to a cosmological term with the time-dependece Λ(t) = Λ(t0) (R(t0)/R(t))P and we examine how values of Ωm and ΩΛ depend on P.

AbstractBlackbody radiation inversion is a mathematical process for the determination of probability distribution of temperature from measured radiated power spectrum. In this paper a simple and stable blackbody radiation inversion is achieved by using an analytical function with three determinable parameters for temperature distribution. This inversion technique is used to invert the blackbody radiation field of the cosmic microwave background, the remnant radiation of the hot big bang, to infer the temperature distribution of the generating medium. The salient features of this distribution are investigated and analysis of this distribution predicts the presence of distortion in the cosmic microwave background spectrum.
