Gravitational instabilities and faster evolving density perturbations
Elcio Abdalla, Roya Mohayaee
The evolution of inhomogeneities in a spherical collapse model is studied by expanding the Einstein equation in powers of inverse radial parameter. In the linear regime, the densit…

Gravitational Clustering to All Perturbative Orders
Elcio Abdalla, Roya Mohayaee
We derive the time evolution of the density contrast to all orders of perturbation theory, by solving the Einstein equation for scale-invariant fluctuations. These fluctuations are…

A Dynamical Approach to a Self-similar Universe
E. Abdalla, N. Afshordi, K. Khodjasteh +1
We write a non-relativistic Lagrangian for a hierarchical universe. The equations of motion are solved numerically and the evolution of the fractal dimension is obtained for differ…
