Statistical Mechanics of gravitating systems in static and cosmological backgrounds
T. Padmanabhan
This pedagogical review addresses several issues related to statistical description of gravitating systems in both static and expanding backgrounds, focusing on the latter. After b…
Gravitational Dynamics in an Expanding Universe
T. Padmanabhan
The dynamical evolution of collisionless particles in an expanding background is described. After discussing qualitatively the key features, the gravitational clustering of collisi…
Evolution Of Gravitational Potential In The Quasilinear And Nonlinear Regimes
J. S. Bagla, T. Padmanabhan
We study the evolution of the power spectrum of gravitational potential during the nonlinear clustering in an matter dominated phase. N-body simulations suggest that the pote…
Constraints on the Models for Structure Formation from the Abundance of Damped Lyman Alpha Systems
K. Subramanian, T. Padmanabhan
Models for structure formation attempt to predict the power spectrum of density perturbations in the present universe from the initial power spectrum and the nature of dark matter.…
Baryonic Content of Galactic Halos and Constraints on Models for Structure Formation
T. Padmanabhan, K. Subramanian
The recent detection of microlensing of stars of LMC by compact objects in the halo of our galaxy suggests that our galaxy is surrounded by a non-luminous halo made of compact obje…
