Static Tidal Perturbations of Relativistic Stars: Corrected Center Expansion and Love Numbers-I
Emel Altas, Ercan Kilicarslan, Onur Oktay +1
We revisit static tidal perturbations of relativistic stars with emphasis on two technical issues in the standard quadrupolar formulation. First, we derive the regular-center Frobe…
Kerr-Schild perturbations in higher derivative gravity theories in dimensions
Ercan Kilicarslan
We study Kerr-Schild perturbations of a ghost-free, generic non-local gravity theory constructed from an infinite series of higher derivative terms in dimensions. The infinite…
Solutions with pure radiation and gyratons in 3D massive gravity theories
Ercan Kilicarslan, Ivan Kolář
We find exact solutions of topologically massive gravity (TMG) and new massive gravity (NMG) in dimensions (3D) with an arbitrary cosmological constant, pure radiation, and…
Anomalous Dispersion in Gravity Theories
Emel Altas, Ercan Kilicarslan, Bayram Tekin
A wave pulse (be it a gravitational wave or a light wave) undergoes anomalous dispersion in a vacuum in flat spacetimes with an even number of spatial dimensions even if all the fr…
Exact gyratons in higher and infinite derivative gravity
Ivan Kolář, Tomáš Málek, Suat Dengiz +1
We study solutions describing spinning null sources called gyratons in generic theories of gravity with terms that are quadratic in curvature and contain an arbitrary number of cov…
Impulsive waves in ghost free infinite derivative gravity in anti-de Sitter spacetime
Suat Dengiz, Ercan Kilicarslan, Ivan Kolář +1
We study exact impulsive gravitational waves propagating in anti-de Sitter spacetime in the context of the ghost free infinite derivative gravity. We show that the source-free theo…
-waves as exact solutions to ghost-free infinite derivative gravity
Ercan Kilicarslan
We construct exact pp-wave solutions of ghost-free infinite derivative gravity and demonstrate that the sourceless theory does not bring any pp-wave solutions save for that of Eins…
On memory effect in modified gravity theories
Ercan Kilicarslan
In this note, we discuss the gravitational memory effect in higher derivative and infinite derivative gravity theories and give the detailed relevant calculations whose results wer…
Weak Field Limit of Infinite Derivative Gravity
Ercan Kilicarslan
A form of infinite derivative gravity is free from ghost-like instabilities with improved small scale behavior. In this theory, we calculate the tree-level scattering amplitude and…
Graviton Mass and Memory
Ercan Kilicarslan, Bayram Tekin
Gravitational memory, a residual change, arises after a finite gravitational wave pulse interacts with free masses. We calculate the memory effect in massive gravity as a function…
