Cosmodynamics: Energy conditions, Hubble bounds, density bounds, time and distance bounds
Celine Cattoen, Matt Visser
We refine and extend a programme initiated by one of the current authors [Science 276 (1997) 88; Phys. Rev. D56 (1997) 7578] advocating the use of the classical energy conditions o…
Fate of gravitational collapse in semiclassical gravity
Carlos Barcelo, Stefano Liberati, Sebastiano Sonego +1
While the outcome of gravitational collapse in classical general relativity is unquestionably a black hole, up to now no full and complete semiclassical description of black hole f…
The Hubble series: Convergence properties and redshift variables
Celine Cattoen, Matt Visser
In cosmography, cosmokinetics, and cosmology it is quite common to encounter physical quantities expanded as a Taylor series in the cosmological redshift z. Perhaps the most well-k…
Buchdahl-like transformations for perfect fluid spheres
Petarpa Boonserm, Matt Visser
In two previous articles [Phys. Rev. D71 (2005) 124307 (gr-qc/0503007), and gr-qc/0607001] we have discussed several "algorithmic" techniques that permit one (in a purely mechanica…
The Kerr spacetime: A brief introduction
Matt Visser
This chapter provides a brief introduction to the Kerr spacetime and rotating black holes, touching on the most common coordinate representations of the spacetime metric and the ke…
Analogue model of a FRW universe in Bose-Einstein condensates: Application of the classical field method
Piyush Jain, Silke Weinfurtner, Matt Visser +1
Analogue models of gravity have been motivated by the possibility of investigating phenomena not readily accessible in their cosmological counterparts. In this paper, we investigat…
