Figure 15: Effective strain at a distance of 100 Mpc shown as a function of the GW frequency (solid
red curve) for the same four merger calculations depicted in Figure 14. Post-merger quasi-periodic
oscillations are seen as broad peaks in the GW spectrum at frequencies = 2 – 4 kHz.
The blue curve shows the Taylor T4 result, which represents a particular method of deducing
the signal from a 3PN evolution. The thick green dashed curve and orange dot-dashed curves
depict the sensitivities of the second-generation Advanced LIGO and LCGT (Large Scale Cryogenic
Gravitational Wave Telescope) detectors, respectively, while the maroon dashed curve shows the
sensitivity of a hypothetical third-generation Einstein Telescope. Image reproduced by permission
