Effects of Solar Wind Plasma Noise on Stochastic Gravitational Wave Background Searches with the LISA-Taiji Network
Mengfei Sun, Borui Wang, Jie Wu +2
The LISA-Taiji dual detector network improves millihertz SGWB sensitivity through cross correlation measurements. Solar wind plasma, however, can generate plasma noise correlated b…
Tests of general relativity using analytic derivatives of parametrized post-Einsteinian gravitational waveforms within the Fisher-matrix framework
Jie Wu, Mengfei Sun, Jin Li
Testing gravity beyond general relativity (GR) is essential for probing fundamental physics in the strong-field and highly dynamical regime accessed by gravitational-wave (GW) obse…
Constraining Kerr supermassive black hole properties using gravitational waves from inspiraling stellar-mass binary black holes
Jie Wu, Jin-Tao Yao, Mengfei Sun +2
We study the capability of future space-based gravitational-wave (GW) detectors to constrain supermassive black hole (SMBH) properties through observations of inspiraling stellar-m…
Identifiability of mode Resonances in Eccentric Binary Neutron Stars with Multidetector Observations
Mengfei Sun, Jie Wu, Qianning Hu +6
mode resonances in eccentric binary neutron star systems are potential probes of internal stratification, superfluidity, composition gradients, and the equation of state. Altho…
Detection of Multiband Lensed Gravitational Waves from Dark Matter Halos with Deep Learning
Mengfei Sun, Jie Wu, Qianning Hu +6
Lensed gravitational waves acquire amplitude and phase modulations when propagating through the gravitational potential of dark matter halos, producing interference structures in t…
Conditional Autoencoder for Generating Binary Neutron Star Waveforms with Tidal and Precession Effects
Mengfei Sun, Jie Wu, Jin Li +5
Gravitational waves from binary neutron star mergers provide critical insights into dense matter physics and strong-field gravity, yet accurate waveform modeling remains computatio…
