Cosmological gravitational wave backgrounds from phase transitions, domain walls, and condensate fragmentation are capped far below the astrophysical foreground by requiring that compact dark matter subhalos, which SKA could probe, are not overproduced.

abstract
We study the impact of the black hole 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 for power-law signals including these astrophysical foregrounds. Even with optimistic assumptions, we find that the reach of future experiments will be severely reduced.

The power of SKA to Constrain cosmological gravitational-wave backgrounds below the astrophysical foreground noise
Cosmological gravitational wave backgrounds from phase transitions, domain walls, and condensate fragmentation are capped far below the astrophysical foreground by requiring that compact dark matter subhalos, which SKA could probe, are not overproduced.
