Investigating the influence of spin-curvature coupling on extreme mass-ratio inspirals
In this report, extreme mass ratio inspiral worldlines and gravitational waveforms were produced considering radiation reaction and spin-curvature effects. Spin-curvature coupling was predicted to modify the inspiral by introducing oscillations to the small body's worldline. Investigating these …

Dense stellar systems and massive black holes
… predictions of this theory are black holes. Massive, dark objects are found in the majority of galaxies. Our own galactic center very contains such an object with a mass of about four million solar masses. Are these objects supermassive black holes (SMBHs), or do we need alternatives? The …

Gravitational Waves From Perturbed Kerr Black Holes: Two Investigations
… produced by the quasicircular, equatorial, extreme mass-ratio inspiral of a compact object into a Kerr black hole of mass M and spin J. For a given dimensionless spin a ≡ J/M2 (in geometrical units G = c = 1 ), the energy flux depends only on the orbital velocity v or (equivalently) on the …

Experimental gravity with electromagnetic and gravitational waves
… the gravitational waves produced when comparable-mass black holes collide; and we have also studied chaotic signatures that could appear when a small compact object falls into a supermassive object during an extreme mass-ratio inspiral. Our analyses combined relativistic ray-tracing and Markov …

Frequency domain approach to self-force calculations
… prospect of detecting gravitational waves from extreme mass ratio inspiral systems, we consider the motion of the particle in black hole spacetimes. As a toy model for the most astrophysically relevant scenario of orbits about a rotating black hole we first study the scalar-field self-force …

Exploring fundamental physics with gravitational waves
… for signals from individually resolvable supermassive black hole binaries. The main obstacle to performing efficient searches is the large size of the data sets, which consist of more than one billion stars. A near-lossless compression which reduces the size of the data set by a factor of …
