Searching for anisotropic stochastic gravitational-wave backgrounds with constellations of space-based interferometers

Understand

Many recent works have shown that the angular resolution of ground-based detectors is too poor to characterize the anisotropies of the stochastic gravitational-wave background (SGWB).

• For this reason, we asked ourselves if a constellation of space-based instruments could be more suitable.
• We consider the Laser Interferometer Space Antenna (LISA), a constellation of multiple LISA-like clusters, and the Deci-hertz Interferometer Gravitational-wave Observatory (DECIGO).
• Specifically, we test whether these detector constellations can probe the anisotropies of the SGWB.
