Black branes and black strings in the astrophysical and cosmological context
Ozgur Akarsu, Alexey Chopovsky, Alexander Zhuk
We consider Kaluza-Klein models where internal spaces are compact flat or curved Einstein spaces. This background is perturbed by a compact gravitating body with the dust-like equa…
Brane world models with bulk perfect fluid and broken 4D Poincare invariance
Ozgur Akarsu, Alexey Chopovsky, Maxim Eingorn +2
We consider 5D brane world models with broken global 4D Poincar\a'{e} invariance (4D part of the spacetime metric is not conformal to the Minkowski spacetime). The bulk is filled w…
Weak-field limit of Kaluza-Klein models with spherically symmetric static scalar field: observational constraints
Alexander Zhuk, Alexey Chopovsky, Seyed Hossein Fakhr +2
In a multidimensional Kaluza-Klein model with Ricci-flat internal space, we study the gravitational field in the weak-field limit. This field is created by two coupled sources. Fir…
