Acoustic wave equation in the expanding universe. Sachs-Wolfe theorem
نویسندگان
چکیده
In this paper the acoustic field propagating in the early hot (p = ǫ/3) universe of arbitrary space curvature (K = 0, ±1) is considered. The field equations are reduced to the d'Alembert equation in an auxiliary static Roberson–Walker space-time. Symbolic computation in Mathematica is applied.

The structural elements of the cosmic web
In 1970 Zel’dovich published a far-reaching paper presenting a simple equation describing the nonlinear growth of primordial density inhomogeneities. The equation was remarkably successful in explaining the large scale structure in the Universe that we observe: a Universe in which the structure appears to be delineated by filaments and clusters of galaxies surrounding huge void regions. In orde...

Working toward a model independent understanding of cosmic microwave background (CMB) anisotropies and their significance, we undertake a comprehensive and self-contained study of scalar perturbation theory. Initial conditions, evolution, thermal history, matter content, background dynamics, and geometry all play a role in determining the anisotropy. By employing analytic techniques to illumina...
متن کاملA High Order Approximation of the Two Dimensional Acoustic Wave Equation with Discontinuous Coefficients
This paper concerns with the modeling and construction of a fifth order method for two dimensional acoustic wave equation in heterogenous media. The method is based on a standard discretization of the problem on smooth regions and a nonstandard method for nonsmooth regions. The construction of the nonstandard method is based on the special treatment of the interface using suitable jump conditio...

We investigate the possibility of constraining Chaplygin dark energy models with current Integrated Sachs Wolfe effect data. In the case of a flat universe we found that generalized Chaplygin gas models must have an energy density such that Ωc > 0.55 and an equation of state w < −0.6 at 95% c.l.. We also investigate the recently proposed Silent Chaplygin models, constraining Ωc > 0.55 and w < −...
متن کاملSolution of propagation of acoustic-gravity waves in the atmosphere using finite difference method of order two
Investigating waves propagation’s equation in the atmosphere is one of the important and widely used issues in various sciences, which has attracted many researchers. A type of propagating waves is an acoustic-gravity wave. These type of waves have a lot of stationarity properties and can be propagate to a high altitude in the atmosphere. The equation of acoustic-gravity wave propagation is a h...
