Nonlinear density evolution from an improved spherical collapse model
S. Engineer, Nissim Kanekar, T. Padmanabhan
We investigate the evolution of non-linear density perturbations by taking into account the effects of deviations from spherical symmetry of a system. Starting from the standard sp…

A formal analysis of two dimensional gravity
S. Engineer, K. Srinivasan, T. Padmanabhan
Several investigations in the study of cosmological structure formation use numerical simulations in both two and three dimensions. In this paper we address the subtle question of…

Nonlinear Gravitational Clustering: dreams of a paradigm
T. Padmanabhan, Sunu Engineer
We discuss the late time evolution of the gravitational clustering in an expanding universe, based on the nonlinear scaling relations (NSR) which connect the nonlinear and linear t…
