Imprint of accretion disk-induced migration on gravitational waves from extreme mass ratio inspirals.
We study the effects of a thin gaseous accretion disk on the inspiral of a stellar-mass black hole into a supermassive black hole. We construct a phenomenological angular momentum transport equation that reproduces known disk effects. Disk torques modify the gravitational wave phase evolution to detectable levels with LISA for reasonable disk parameters. The Fourier transform of disk-modified w...
متن کاملGravitational waves from extreme mass ratio inspirals: Challenges in mapping the spacetime of massive, compact objects
In its final year of inspiral, a stellar mass (1− 10M⊙) body orbits a massive (10 − 10M⊙) compact object about 10 times, spiralling from several Schwarzschild radii to the last stable orbit. These orbits are deep in the massive object’s strong field, so the gravitational waves that they produce probe the strong field nature of the object’s spacetime. Measuring these waves can, in principle, be ...
متن کاملGravitational wave snapshots of generic extreme mass ratio inspirals
Using black hole perturbation theory, we calculate the gravitational waves produced by test particles moving on bound geodesic orbits about rotating black holes. The orbits we consider are generic — simultaneously eccentric and inclined. The waves can be described as having radial, polar, and azimuthal “voices”, each of which can be made to dominate by varying eccentricity and inclination. Alth...
متن کاملGravitational self force in extreme mass-ratio inspirals
This review is concerned with the gravitational self-force acting on a mass particle in orbit around a large black hole. Renewed interest in this old problem is driven by the prospects of detecting gravitational waves from strongly gravitating binaries with extreme mass ratios. We begin here with a summary of recent advances in the theory of gravitational self-interaction in curved spacetime, a...
متن کاملGravitational radiation timescales for extreme mass ratio inspirals
The capture and inspiral of compact stellar objects into massive black holes is an important source of low-frequency gravitational waves (with frequencies ∼ 1 − 100mHz), such as those that might be detected by the planned Laser Interferometer Space Antenna (LISA). Simulations of stellar clusters designed to study this problem typically rely on simple treatments of the black hole encounter which...
