Fast and Fourier: Extreme Mass Ratio Inspiral Waveforms in the Frequency Domain

Understand

Extreme Mass Ratio Inspirals (EMRIs) are one of the key sources for future space-based gravitational wave interferometers.

• Measurements of EMRI gravitational waves are expected to determine the characteristics of their sources with sub-percent precision.
• However, their waveform generation is challenging due to the long duration of the signal and the high harmonic content.
• Here, we present the first ready-to-use Schwarzschild eccentric EMRI waveform implementation in the frequency domain for use with either graphics processing units (GPUs) or central processing units (CPUs).
