Impact of LIGO-Virgo binaries on gravitational wave background searches
  We study the impact of the binary population currently probed by LIGO-Virgo
on future searches for the primordial gravitational wave background. We
estimate the foreground generated by the binaries using the observed event rate
and a simple modeling of the black hole population. We subtract individually
resolvable binaries from the foreground and utilize Fisher analysis to derive
sensitivity curves similar to the power-law integrated prescription. We find
that despite this improved treatment the reach of future experiments will still
be severely impacted.
