Static spherically symmetric scalar field spacetimes with C^0 matching

Swastik Bhattacharya, Pankaj S. Joshi

All the classes of static massless scalar field models available currently in the Einstein theory of gravity necessarily contain a strong curvature naked singularity. We obtain her…

Accelerated cosmic expansion in a scalar-field universe

Swastik Bhattacharya, Pankaj S. Joshi, Ken-ichi Nakao

We consider here a spherically symmetric but inhomogeneous universe filled with a massless scalar field. The model obeys two constraints. The first one is that the gradient of the…

Black Holes in Active Galactic Nuclei

M. J. Valtonen, S. Mikkola, D. Merritt +7

Supermassive black holes are common in centers of galaxies. Among the active galaxies, quasars are the most extreme, and their black hole masses range as high as to $6\cdot 10^{10}…

Radiation from collapsing shells, semiclassical backreaction and black hole formation

Aseem Paranjape, T. Padmanabhan

We provide a detailed analysis of quantum field theory around a collapsing shell and discuss several conceptual issues related to the emission of radiation flux and formation of bl…

Non-marginal LTB-like models with inverse triad corrections from loop quantum gravity

Martin Bojowald, Juan D. Reyes, Rakesh Tibrewala

Marginal LTB models with corrections from loop quantum gravity have recently been studied with an emphasis on potential singularity resolution. This paper corroborates and extends…

Quantum theory, noncommutative gravity, and the cosmological constant problem

T. P. Singh

The cosmological constant problem is principally concerned with trying to understand how the zero-point energy of quantum fields contributes to gravity. Here we take the approach t…
