Weyl fluid dark matter model tested on the galactic scale by weak gravitational lensing
K. C. Wong, T. Harko, K. S. Cheng +1
The higher dimensional Weyl curvature induces on the brane a new source of gravity. This Weyl fluid of geometrical origin (reducing in the spherically symmetric, static configurati…
Inflating wormholes in the braneworld models
K. C. Wong, T. Harko, K. S. Cheng
The braneworld model, in which our Universe is a three-brane embedded in a five-dimensional bulk, allows the existence of wormholes, without any violation of the energy conditions.…
Inflation and late time acceleration in braneworld cosmological models with varying brane tension
K. C. Wong, K. S. Cheng, T. Harko
Braneworld models with variable brane tension introduce a new degree of freedom that allows for evolving gravitational and cosmological constants, the latter being a natural ca…
Reheating the Universe in Braneworld Cosmological Models with bulk-brane energy transfer
T. Harko, W. F. Choi, K. C. Wong +1
The emergence of the cosmological composition (the reheating era) after the inflationary period is analyzed in the framework of the braneworld models, in which our Universe is a th…
