Teleparallel Theories of Gravity: Illuminating a Fully Invariant Approach
M. Krssak, R. J. van den Hoogen, J. G. Pereira +2
Teleparallel gravity and its popular generalization gravity can be formulated as fully invariant (under both coordinate transformations and local Lorentz transformations) th…
Galactic dark matter as a bulk effect on the brane
C. G. Boehmer, T. Harko
The behavior of the angular velocity of a test particle moving in a stable circular orbit in the vacuum on the brane is considered. In the brane world scenario, the four dimensiona…
On Einstein clusters as galactic dark matter halos
C. G. Boehmer, T. Harko
We consider global and gravitational lensing properties of the recently suggested Einstein clusters of WIMPs as galactic dark matter halos. Being tangential pressure dominated, Ein…
The Einstein-Elko system -- Can dark matter drive inflation?
C. G. Boehmer
Recently, a spin one half matter field with mass dimension one was discovered, called Elko spinors. The present work shows how to introduce these fields into a curved spacetime by…
Dark energy as a massive vector field
C. G. Boehmer, T. Harko
We propose that the Universe is filled with a massive vector field, non-minimally coupled to gravitation. The field equations of the model are consistently derived and their applic…
Bounds on the basic physical parameters for anisotropic compact general relativistic objects
C. G. Boehmer, T. Harko
We derive upper and lower limits for the basic physical parameters (mass-radius ratio, anisotropy, redshift and total energy) for arbitrary anisotropic general relativistic matter…
