An analytic approach to the late ISW effect in a Lambda dominated universe
Viktor Czinner, Mátyás Vasúth, Árpád Lukács
The integrated Sachs-Wolfe (ISW) effect in a Lambda dominated universe can be an important factor in the evolution of cosmic microwave background fluctuations. With the inclusion o…
Covariant Linear Perturbations in a Concordance Model
Viktor Czinner, Mátyás Vasúth, Árpád Lukács +1
We present the complete solution of the first order metric and density perturbation equations in a spatially flat (K=0), Friedmann-Robertson-Walker (FRW) universe filled with press…
perturbations of FRW models with a cosmological constant
Zoltán Perjés, Mátyás Vasúth, Viktor Czinner +1
Spatially homogeneous and isotropic cosmological models, with a perfect fluid matter source and non-vanishing cosmological constant, are studied. The equations governing linear per…
