Detectability of stochastic gravitational wave background from weakly hyperbolic encounters
Morteza Kerachian, Sajal Mukherjee, Georgios Lukes-Gerakopoulos +1
We compute the stochastic gravitational wave (GW) background generated by black hole-black hole (BH-BH) hyperbolic encounters with eccentricities close to one and compare them with…
Action-Angle formalism for extreme mass ratio inspirals in Kerr spacetime
Morteza Kerachian, Lukáš Polcar, Viktor Skoupý +2
We introduce an action-angle formalism for bounded geodesic motion in Kerr black hole spacetime using canonical perturbation theory. Namely, we employ a Lie series technique to pro…
Dynamics of classes of barotropic fluids in spatially curved FRW spacetimes
Morteza Kerachian, Giovanni Acquaviva, Georgios Lukes-Gerakopoulos
In this article we perform dynamical analysis of a broad class of barotropic fluids in the spatially curved Friedmann-Robertson-Walker (FRW) spacetime background without considerin…
Uniformly accelerated traveler in an FLRW universe
Morteza Kerachian
This paper provides an analytical treatment of accelerated and geodesic motion within the framework of the Friedmann -Lemaitre-Robertson-Walker (FLRW) spacetime. By employing confo…
Classes of non-minimally coupled scalar fields in spatially curved FRW spacetimes
Morteza Kerachian, Giovanni Acquaviva, Georgios Lukes-Gerakopoulos
In this work we perform a dynamical analysis of a broad class of non-minimally coupled real scalar fields in the Friedmann-Robertson-Walker (FRW) spacetime framework. The first par…
A scan of f(R) models admitting Rindler type acceleration
S. Habib Mazharimousavi, M. Kerachian, M. Halilsoy
As a manifestation of large distance effect Grumiller modified Schwarzschild metric with an extraneous term reminiscent of Rindler acceleration. Such a term has the potential to ex…
Existence of Reissner-Nordstrom type black holes in f(R) gravity
S. Habib Mazharimousavi, M. Kerachian, M. Halilsoy
We investigate the existence of Reissner-Nordström (RN) type black holes in f(R) gravity. Our emphasis is to derive, in the presence of electrostatic source, the necessary conditio…
