Alternative LISA-TAIJI networks

The space-borne gravitational wave (GW) detectors, LISA and TAIJI, are planned to be launched in the 2030s. dual detectors with comparable sensitivities will form a network observing GW significant advantages. In this work, we investigate three possible LISA-TAIJI networks for different location orientation compositions of orbit ($+60^\circ$ inclination trailing Earth by $20^\circ$) alternative TAIJI configurations including TAIJIp leading $20^\circ$), TAIJIc co-located LISA), TAIJIm ($-60^\circ$ $20^\circ$). configurations, LISA-TAIJIm shows best performance on sky localization polarization determination massive binary system due their better complementary antenna pattern, LISA-TAIJIc could achieve cross-correlation observe stochastic background an optimal sensitivity.
