Shadow cast of non-commutative black holes in Rastall gravity

Ali Övgün, İzzet Sakallı, Joel Saavedra +1

We study the shadow and energy emission rate of a spherically symmetric non-commutative black hole in Rastall gravity. Depending on the model parameters, the non-commutative black…

GUP Modified Hawking Radiation in Bumblebee Gravity

Sara Kanzi, İzzet Sakallı

The effect of Lorentz symmetry breaking (LSB) on the Hawking radiation of Schwarzschild-like black hole found in the bumblebee gravity model (SBHBGM) is studied in the framework of…

Greybody Factors of Holographic Superconductors with Lifshitz Scaling

Huriye Gürsel, İzzet Sakallı

We study the quasinormal modes and thermal radiation of massless spin-0 field perturbations in the background of four-dimensional (4D) non-Abelian charged Lifshitz black branes wit…

Higher Dimensional Particle Model in Third-Order Lovelock Gravity

S. Danial Forghani, S. Habib Mazharimousavi, Mustafa Halilsoy

By using the formalism of thin-shells, we construct a geometrical model of a particle in third-order Lovelock gravity. This particular theory which is valid at least in 7 dimension…

Hawking Radiation via Gauss-Bonnet Theorem

A. Övgün, İ. Sakallı

In this paper, we apply the topological method to the various black holes to derive their Hawking temperature. We show that the this method can easily be employed to compute the Ha…
