Modeling extreme mass ratio inspirals within the effective-one-body approach.
We present the first models of extreme-mass-ratio inspirals within the effective-one-body (EOB) formalism, focusing on quasicircular orbits into nonrotating black holes. We show that the phase difference and (Newtonian-normalized) amplitude difference between analytical EOB and numerical Teukolsky-based gravitational waveforms can be reduced to less than or approximately 10{-1} rad and less tha...
متن کاملDetection Strategies for Extreme Mass Ratio Inspirals
The capture of compact stellar remnants by galactic black holes provides a unique laboratory for exploring the near horizon geometry of the Kerr spacetime. The gravitational radiation produced by these Extreme Mass Ratio Inspirals (EMRIs) encodes a detailed map of the black hole geometry, and the detection and characterization of these signals is a major science driver for the LISA observatory....
متن کاملStrategies for observing extreme mass ratio inspirals
I review the status of research, conducted by a variety of independent groups, aimed at the eventual observation of Extreme Mass Ratio Inspirals (EMRIs) with gravitational wave detectors. EMRIs are binary systems in which one of the objects is much more massive than the other, and which are in a state of dynamical evolution that is dominated by the effects of gravitational radiation. Although t...
متن کامل(Sort of) Testing relativity with extreme mass ratio inspirals
The inspirals of “small” (1−100M⊙) compact bodies through highly relativistic orbits of massive (several ×105 M⊙− several ×106 M⊙) black holes are among the most anticipated sources for the LISA gravitational-wave antenna. The measurement of these waves is expected to map the spacetime of the larger body with high precision, allowing us to test in detail the hypothesis that black hole candidate...
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...
