Straight and Wiggly Cosmic Strings in Horndeski Theory
M. Haluk Seçuk, Özgür Delice
In this article, the behavior of a straight cosmic string is studied for the linearized version of Horndeski theory in cases where the scalar field is massless or massive. Several…
Innermost stable circular orbits around a Reissner-Nordström-global monopole spacetime in a homogeneous magnetic field
Hamza M. Haddad, M. Haluk Seçuk, Özgür Delice
We investigate the dynamics of charged particles in the spacetime of a global monopole swallowed by a Reissner-Nordström (RN) black hole in the presence of an external, weak, asymp…
Gravitational waves in Brans-Dicke Theory with a cosmological constant
Hatice Özer, Özgür Delice
Weak field gravitational wave solutions are investigated in Brans-Dicke (BD) theory in the presence of a cosmological constant. In this setting the background geometry is not flat…
Bending of Light from Reissner-Nordström-de Sitter-Monopole Black Hole
M. Haluk Seçuk, Özgür Delice
We study light deflection from a Reissner-Nordström-de Sitter black hole in the gravitational monopole background. We first calculate the orbit equation and the contribution of the…
Superradiance of a Global Monopole in Reissner-Nordström(-AdS) Space-time
M. Haluk Seçuk, Özgür Delice
In this article, the behaviour of a charged and massive scalar field around a global monopole swallowed by a Reissner-Nordström-Anti-de Sitter (RN-AdS) black hole is investigated b…
Static Cylindrical Matter Shells
Metin Arik, Ozgur Delice
Static cylindrical shells composed of massive particles arising from matching of two different Levi-Civita space-times are studied for the shell satisfying either isotropic or anis…
