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

个人简介：Dr. Gang Wang received his Ph.D. from Gran Sasso Science Institute/SISSA in 2017 and worked on the data analysis pipeline searching for gravitational wave signals from compact binary coalescence in the LIGO-Virgo collaboration during 2015-2017. After one year of visiting at Wuhan Institute of Physics and Mathematics, CAS, he joins the Gravitational Wave and Relativistic Fundamental Astronomy Group in Shanghai Astronomical Observatory, CAS in 2019 and works on gravitational wave data analysis.
