Searching for cosmological gravitational-wave backgrounds with third-generation detectors in the presence of an astrophysical foreground
Ashish Sharma, J. Harms
Abstract
Third-generation gravitational-wave detectors, such as the Einstein Telescope and the Cosmic Explorer, are projected to be not only extremely sensitive instruments for detecting compact binary coalescences but also the cosmological gravitational-wave background. However, in order to delineate the stochastic cosmological gravitational-wave background in the observed data, the astrophysical foreground needs to be subtracted. This paper proposes a method to achieve this to make these new GW detectors instruments of cosmology.
