On networks of space-based gravitational-wave detectors
Rong-Gen Cai, Zong-Kuan Guo, Bin Hu +7
The space-based laser interferometers, LISA, Taiji and TianQin, are targeting to observe milliHz gravitational waves (GWs) in the 2030s. The joint observations from multiple space-…
Investigating galactic double white dwarfs for sub-milliHz gravitational wave mission ASTROD-GW
Gang Wang, Zhen Yan, Bin Hu +1
A large number of galactic binary systems emit gravitational waves (GW) continuously with frequencies below 10 mHz. The LISA mission could identify tens of thousands of binar…
Alternative LISA-TAIJI networks: detectability of the isotropic stochastic gravitational wave background
Gang Wang, Wen-Biao Han
In previous work [1], three TAIJI orbital deployments have been proposed to compose alternative LISA-TAIJI networks, TAIJIm (leading the Earth by and incline…
Alternative LISA-TAIJI networks
Gang Wang, Wei-Tou Ni, Wen-Biao Han +2
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 obs…
Algorithm for TDI numerical simulation and sensitivity investigation
Gang Wang, Wei-Tou Ni, Wen-Biao Han +1
We introduce a generic algorithm to determine the time delays and spacecraft (S/C) positions to compose any time-delay interferometry (TDI) channel in the dynamical case and evalua…
Revisiting time delay interferometry for unequal-arm LISA and TAIJI
Gang Wang, Wei-Tou Ni
Three spacecraft of LISA/TAIJI mission follow their respective geodesic trajectories, and their interferometric arms are unequal and time-varying due to orbital dynamics. Time-dela…
Investigating eccentricities of the binary black hole signals from the LIGO-Virgo catalog GWTC-1
Qian-Yun Yun, Wen-Biao Han, Gang Wang +1
In the first Gravitational-Wave Transient Catalogue of LIGO and Virgo, all events are announced having zero eccentricity. In the present paper, we investigate the performance of SE…
Numerical simulation of sky localization for LISA-TAIJI joint observation
Gang Wang, Wei-Tou Ni, Wen-Biao Han +2
LISA is considered to be launched alongside the Athena to probe the energetic astrophysical processes. LISA can determine the direction of sources for Athena's follow-up observatio…
DEEM, a versatile platform of FRD measurement for highly multiplexed fibre systems in astronomy
Yunxiang Yan, Qi Yan, Gang Wang +6
We present a new method of DEEM, the direct energy encircling method, for characterising the performance of fibres in most astronomical spectroscopic applications. It's a versatile…
A modified method for determining the FRD and length properties of optical fibres in astronomy
Yunxiang Yan, Gang Wang, Weimin Sun +4
Focal ratio degradation (FRD) is a major contributor to throughput and light loss in a fibre spectroscopic telescope system. We combine the guided mode theory in geometric optics a…
Astrodynamical middle-frequency interferometric gravitational wave observatory AMIGO: Mission concept and orbit design
