Cosmic Inhomogeneities and the Average Cosmological Dynamics
Aseem Paranjape, T. P. Singh
If general relativity (GR) describes the expansion of the Universe, the observed cosmic acceleration implies the existence of a `dark energy'. However, while the Universe is on ave…
Classical and Quantum Gravitational Collapse in d-dim AdS Spacetime II. Quantum States and Hawking Radiation
Cenalo Vaz, Rakesh Tibrewala, T. P. Singh
In a previous paper we studied the collapse of a spherically symmetric dust distribution (marginally bound LTB) in d-dimensional AdS spacetime and obtained the condition for the fo…
Classical and Quantum Gravitational Collapse in d-dim AdS Spacetime I. Classical Solutions
Rakesh Tibrewala, Sashideep Gutti, T. P. Singh +1
We study the collapse of a spherically symmetric dust distribution in -dimensional AdS spacetime. We investigate the role of dimensionality, and the presence of a negative cosmo…
Particle creation in (2+1) circular dust collapse
Sashideep Gutti, T. P. Singh
We investigate the quantum particle creation during the circularly symmetric collapse of a 2+1 dust cloud, for the cases when the cosmological constant is either zero or negative.…
The Spatial Averaging Limit of Covariant Macroscopic Gravity - Scalar Corrections to the Cosmological Equations
Aseem Paranjape, T. P. Singh
It is known that any explicit averaging scheme of the type essential for describing the large scale behaviour of the Universe, must necessarily yield corrections to the Einstein eq…
