(Springer, 2016-05-27)
Potentiality of the presence of traversable wormholes in the outer/inner regions of the halos of galaxies, situated on the Navarro-Frenk-White (NFW) density profile and Universal Rotation Curve (URC) dark matter models ...

(Astroparticle Physics, Elsevier, 2016)
We analytically study the scalar perturbation of non-asymptotically flat (NAF) rotating linear dilaton black holes (RLDBHs) in 4-dimensions. We show that both radial and angular wave equations can be solved in terms of the ...

(The European Physical Journal C, Springer, 2014-03-13)
We revisit the regular black hole found by Hayward in 4 -dimensional static, spherically symmetric spacetime. To find a possible source for such a spacetime we resort to the nonlinear electrodynamics in general relativity. ...

(World Scientific Publishing, 2014-06-24)
In this paper, we analyze the Hawking radiation (HR) of a non-asymptotically flat (NAF) dyonic black hole (dBH) in four-dimensional (4D) Einstein–Maxwell–Dilaton (EMD) gravity by using one of the semiclassical approaches ...

Sakallı, İzzet; Övgün, Ali; Kimet, Jusufi
(Springer, 2016-09-13)
Recent studies (Steinhauer in Nat. Phys. 10:864, 2014, Phys. Rev. D 92:024043, 2015) provide compelling evidences that Hawking radiation could be experimentally proven by using an analogue black hole. In this paper, taking ...

Gürsel, Huriye
(Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2015-09)
This thesis mainly focuses on the Hawking radiation (HR) evacuating from the
surface of the objects that have earned a reputation as the most extraordinary objects
existing so far; the black holes (BHs). Throughout this ...

(Eastern Mediterranean University (EMU), 2013)
ABSTRACT: The identity of dark matter is one of the key outstanding problems in both particle and astrophysics. In this thesis, I review some candidates of dark matter, especially WIMPs (weakly interacting massive particles) ...

Hamo, Alan Hameed Hussein
(Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2014-08)
In this thesis, we investigate the geodesics of the 4-dimensional (4D) linear dilaton
black hole (LDBH), which is an exact solution to the Einstein-Maxwell-Dilaton
(EMD) theory. These spacetimes have non-asymptotically ...

Övgün, Ali
(Izmir Institute of Technology - İzmir Yüksek Teknoloji Enstitüsü, 2010)
Thıs is my undergraduate thesis. So far I have worked on tunneling and its classi-cal, semi-classical and quantum description, then I looked some unsolved problems . Ihave learned about Hartman e ect , ...
