Thin accretion disks onto brane world black holes
C. S. J. Pun, Z. Kovacs, T. Harko
The braneworld description of our universe entails a large extra dimension and a fundamental scale of gravity that might be lower by several orders of magnitude as compared to the…
Electromagnetic signatures of thin accretion disks in wormhole geometries
Tiberiu Harko, Zoltán Kovács, Francisco S. N. Lobo
In this paper, we study the physical properties and characteristics of matter forming thin accretion disks in static and spherically symmetric wormhole spacetimes. In particular, t…
Thin accretion disks in f(R) modified gravity models
C. S. J. Pun, Z. Kovacs, T. Harko
We consider the basic physical properties of matter forming a thin accretion disc in the static and spherically symmetric space-time metric of the vacuum modified gravity mo…
Viscous dissipative Chaplygin gas dominated homogenous and isotropic cosmological models
C. S. J. Pun, L. Á. Gergely, M. K. Mak +3
The generalized Chaplygin gas, which interpolates between a high density relativistic era and a non-relativistic matter phase, is a popular dark energy candidate. We consider a gen…
