Modelling of gravitational waves from binary black hole inspiral has played an important role in the recent observations of such signals. The late-stage ringdown phase of the gravitational waveform is often associated with the null particle orbit ("light ring") of the black hole spacetime. With simple models we show that this link between the light ring and spacetime ringing is based more on the history of specific models than on an actual constraining relationship. We also show, in particular… Expand

Merger estimates for rotating Kerr black holes in modified gravity
In this paper, we explore the signatures of non-rotating and rotating black hole mergers in the matter-free modified gravity. First, we solve the unstable circular null orbits and the innermostExpand
Merger estimates for Kerr-Sen black holes
The advent of gravitational wave observation starts a new era of precision tests of gravitational theory. Estimations of black holes mergers should come from any well established gravitationalExpand

TOWARDS PROBING THE STRONG FIELD GRAVITY USING BINARY BLACK-HOLE RINGDOWNS
In this thesis, we study black hole ringdowns as a probe to understand the strong-field clssical gravity. When two black holes merge, they form a single distorted black hole that then radiatesExpand
Testing pseudo-complex general relativity with gravitational waves
We show how the model of pseudo-complex general relativity can be tested using gravitational wave signals from coalescing compact objects. The model, which agrees with Einstein gravity in theExpand
Gravitational wave echoes from black hole area quantization
Gravitational-wave astronomy has the potential to substantially advance our knowledge of the cosmos, from the most powerful astrophysical engines to the initial stages of our universe. GravitationalExpand
On choosing the start time of binary black hole ringdowns
The final stage of a binary black hole merger is ringdown, in which the system is described by a Kerr black hole with quasinormal mode perturbations. It is far from straightforward to identify theExpand
Excitation of Kerr quasinormal modes in extreme-mass-ratio inspirals
If a small compact object orbits a black hole, it is known that it can excite the black hole's quasinormal modes (QNMs), leading to high-frequency oscillations ("wiggles") in the radiated field atExpand
Exciting black hole modes via misaligned coalescences: II. The mode content of late-time coalescence waveforms.
Using inspiral and plunge trajectories we construct with a generalized Ori-Thorne algorithm, we use a time-domain black hole perturbation theory code to compute the corresponding gravitational waves.Expand
Exploring strong-field deviations from general relativity via gravitational waves
Two new observational windows have been opened to strong gravitational physics: gravitational waves, and very long baseline interferometry. This suggests observational searches for new phenomena inExpand
