Rotating galactic black holes
Chao Zhang, Guoyang Fu, Chunyu Zhang
The galactic black hole is a supermassive black hole located at the center of a galaxy surrounded by a dark matter halo. For the first time, we establish a generic, fully-relativis…
Probing the equation of state of neutron stars with captured primordial black holes
Qing Gao, Ning Dai, Yungui Gong +3
Gravitational waves (GWs) from primordial black holes (PBHs) inspiraling within neutron stars (NSs) -- should they exist -- are detectable by ground-based detectors and offer a uni…
Testing alternative theories of gravity with space-based gravitational wave detectors
Qing Gao, Yujie You, Yungui Gong +2
We use gravitational waves (GWs) from binary black holes (BBHs) and neutron stars inspiraling into intermediate-mass black holes to evaluate how accurately the future space-based G…
R-matrix electron-impact excitation data for the H- and He-like ions with Z=6-30
Junjie Mao, G. Del Zanna, Liyi Gu +2
Plasma models built on extensive atomic data are essential to interpreting the observed cosmic spectra. H-like Lyman series and He-like triplets observable in the X-ray band are po…
Source localizations with the network of space-based gravitational wave detectors
Chunyu Zhang, Yungui Gong, Chao Zhang
The sky localization of the gravitational wave (GW) source is an important scientific objective for GW observations. A network of space-based GW detectors dramatically improves the…
Parameter estimation for space-based gravitational wave detectors with ringdown signals
Chunyu Zhang, Yungui Gong, Chao Zhang
Unlike ground-based gravitational wave detectors, space-based gravitational wave detectors can detect the ringdown signals from massive black hole mergers with large signal-to-nois…
Detection of gravitational wave mixed polarization with single space-based detectors
Chao Zhang, Yungui Gong, Dicong Liang +1
General Relativity predicts only two tensor polarization modes for gravitational waves while at most six possible polarization modes are allowed in general metric theory of gravity…
Accuracy of estimation of parameters with space-borne gravitational wave observatory
Chao Zhang, Yungui Gong, Bin Wang +1
Employing the Fisher information matrix analysis, we estimate parameter errors of TianQin and LISA for monochromatic gravitational waves. With the long-wavelength approximation we…
Sky localization of space-based gravitational wave detectors
Chao Zhang, Yungui Gong, Hang Liu +2
Localizing the sky position of the gravitational wave source is a key scientific goal for gravitational wave observations. Employing the Fisher information matrix approximation, we…
Full analytical formulas for frequency response of space-based gravitational wave detectors
Chunyu Zhang, Qing Gao, Yungui Gong +3
The discovery of gravitational waves, which are ripples of space-time itself, opened a new window to test general relativity, because it predicts that there are only plus and cross…
Frequency response of time-delay interferometry for space-based gravitational wave antennas
Chunyu Zhang, Qing Gao, Yungui Gong +3
Space-based gravitational wave detectors cannot keep rigid structures and precise arm length equality, so the precise equality of detector arms which is required in a ground-based…
Frequency response of space-based interferometric gravitational-wave detectors
Dicong Liang, Yungui Gong, Alan J. Weinstein +2
Gravitational waves are perturbations of the metric of space-time. Six polarizations are possible, although general relativity predicts that only two such polarizations, tensor plu…
