Critical Collapse of Einstein Cluster

Ashutosh Mahajan, Tomohiro Harada, Pankaj S. Joshi +1

We observe critical phenomena in spherically symmetric gravitational collapse of Einstein Cluster. We show analytically that the collapse evolution ends either in formation of a bl…

Analytical solutions for black-hole critical behaviour

Tomohiro Harada, Ashutosh Mahajan

Dynamical Einstein cluster is a spherical self-gravitating system of counterrotating particles, which may expand, oscillate and collapse. This system exhibits critical behaviour in…

Self-similar cosmological solutions with dark energy. II: black holes, naked singularities and wormholes

Hideki Maeda, Tomohiro Harada, B. J. Carr

We use a combination of numerical and analytical methods, exploiting the equations derived in a preceding paper, to classify all spherically symmetric self-similar solutions which…

Self-similar cosmological solutions with dark energy. I: formulation and asymptotic analysis

Tomohiro Harada, Hideki Maeda, B. J. Carr

Based on the asymptotic analysis of ordinary differential equations, we classify all spherically symmetric self-similar solutions to the Einstein equations which are asymptotically…

Black Hole Evaporation in an Expanding Universe

Hiromi Saida, Tomohiro Harada, Hideki Maeda

We calculate the quantum radiation power of black holes which are asymptotic to the Einstein-de Sitter universe at spatial and null infinities. We consider two limiting mass accret…
