Cosmological perturbation theory using generalized Einstein de Sitter cosmologies
Michael Joyce, Azrul Pohan
The separable analytical solution in standard perturbation theory for an Einstein de Sitter (EdS) universe can be generalized to the wider class of such cosmologies (``generalized…

Testing growth rate dependence in cosmological perturbation theory using scale-free models
Azrul Pohan, Michael Joyce, David Benhaiem +1
We generalize previously derived analytic results for the one-loop power spectrum (PS) in scale-free models (with linear PS ) to a broader class of such models in…
