Straight and Wiggly Cosmic Strings in Horndeski Theory
M. Haluk Seçuk, Ãzgür 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…

Gravitational waves in massive Horndeski theory with a potential
Hatice Ãzer, Ãzgür Delice
We investigate gravitational waves with an arbitrary potential within the framework of linearized Horndeski theory. We show that the minimum of the potential can play the role of a…

Innermost stable circular orbits around a Reissner-Nordström-global monopole spacetime in a homogeneous magnetic field
Hamza M. Haddad, M. Haluk Seçuk, Ãzgür 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, asym…
