Archival searches for stellar-mass binary black holes in LISA

Understand

Stellar-mass binary black holes will sweep through the frequency band of the Laser Interferometer Space Antenna (LISA) for months to years before appearing in the audio-band of ground-based gravitational-wave detectors.

• One can expect several tens of these events up to a distance of $500 \,\mathrm{Mpc}$ each year.
• The LISA signal-to-noise ratio for such sources even at these close distances will be too small for a blind search to confidently detect them.
• However, next generation ground-based gravitational-wave detectors, expected to be operational at the time of LISA, will observe them with signal-to-noise ratios of several thousands and measure their parameters very accurately.
