The general static spherical perfect fluid solution with EoS parameter w=-1/6
İbrahim Semiz
The general analytical solution for the static spherically symmetric metric supported by a perfect fluid with proportional-equation-of-state is not known at the time of t…
Weak Cosmic Censorship, Superradiance and Quantum Particle Creation
İbrahim Semiz, Koray Düztaş
Since 1970's, gedanken experiments have been devised to challenge the weak cosmic censorship conjecture (WCCC), which is the expectation that spacetime singularities will be hidden…
Cosmic Censorship, Black Holes and Integer-spin Test Fields
Koray Düztaş, İbrahim Semiz
It has been argued that, starting with a slightly sub-extremal Kerr black hole instead of an extremal one, it is possible to overspin a black hole past the extremal limit and turn…
LRS Bianchi type I universes exhibiting Noether symmetry in the scalar-tensor Brans-Dicke theory
Y. Kucukakca, U. Camci, İ. Semiz
Following up on hints of anisotropy in the cosmic microwave background radiation (CMB) data, we investigate locally rotational symmetric (LRS) Bianchi type I spacetimes with non-mi…
The Dirac Equation Is Separable On The Dyon Black Hole Metric
İbrahim Semiz
Using the tetrad formalism, we carry out the separation of variables for the massive complex Dirac equation in the gravitational and electromagnetic field of a four-parameter (mass…
