Thick Lunar Crust Amplifies Deci-Hertz Gravitational-Wave Signal
Lei Zhang, Han Yan, Xian Chen +1
Gravitational waves (GWs) in the Hz band encode unique signatures of the early universe and merging compact objects, but they are beyond the reach of existing observato…
Gravitational radiation from Kerr black holes using the Sasaki-Nakamura formalism: Waveforms and fluxes at infinity
Yucheng Yin, Rico K. L. Lo, Xian Chen
In linear perturbation theory for Kerr black holes, there are two equivalent formalisms, namely the Teukolsky and the Sasaki-Nakamura (SN) formalism. Typically, one defaults to the…
Towards Realistic Detection Pipelines of Taiji: New Challenges in Data Analysis and High-Fidelity Simulations of Space-Based Gravitational Wave Antenna
Minghui Du, Pengcheng Wang, Ziren Luo +23
Taiji, a Chinese space-based gravitational wave (GW) detection project, aims to explore the millihertz GW universe with unprecedented sensitivity. By observing astrophysical and co…
Relativistic model of binary extreme-mass-ratio inspiral systems and their gravitational radiation
Yucheng Yin, Josh Mathews, Alvin J. K. Chua +1
A binary extreme-mass-ratio inspiral (b-EMRI) is a hierarchical triple system consisting of a stellar-mass binary black hole (BBH) orbiting a central Kerr supermassive black hole (…
Gravitational wave ringdown analysis using the -statistic
Hai-Tian Wang, Garvin Yim, Xian Chen +1
After the final stage of the merger of two black holes, the ringdown signal takes an important role on providing information about the gravitational dynamics in strong field. We in…
Constraining the stochastic gravitational wave background using the future lunar seismometers
Han Yan, Xian Chen, Jinhai Zhang +3
Motivated by the old idea of using the moon as a resonant gravitational-wave (GW) detector, as well as the recent updates in modeling the lunar response to GWs, we re-evaluate the…
Towards a Consistent Calculation of the Lunar Response to Gravitational Waves
Han Yan, Xian Chen, Jinhai Zhang +3
The recent increasing interest in detecting gravitational waves (GWs) by lunar seismic measurement urges us to have a clear understanding of the response of the moon to passing GWs…
Calculating the Gravitational Waves Emitted from High-speed Sources
Han Yan, Xian Chen, Alejandro Torres-Orjuela
The possibility of forming gravitational-wave sources with high center-of-mass (c.m.) velocities in the vicinity of supermassive black holes requires us to develop a method of deri…
Astrophysics with the Laser Interferometer Space Antenna
Pau Amaro Seoane, Jeff Andrews, Manuel Arca Sedda +156
The Laser Interferometer Space Antenna (LISA) will be a transformative experiment for gravitational wave astronomy, and, as such, it will offer unique opportunities to address many…
Amplification of gravitational wave by a Kerr black hole
Yi Gong, Zhoujian Cao, Xian Chen
Binary black hole may form near a supermassive black hole. The background black hole (BH) will affect the gravitational wave (GW) generated by the binary black hole. It is well kno…
The missing link in gravitational-wave astronomy: A summary of discoveries waiting in the decihertz range
Manuel Arca Sedda, Christopher P L Berry, Karan Jani +25
Since 2015 the gravitational-wave observations of LIGO and Virgo have transformed our understanding of compact-object binaries. In the years to come, ground-based gravitational-wav…
Exciting modes due to the aberration of gravitational waves: Measurability for extreme-mass-ratio inspirals
Alejandro Torres-Orjuela, Pau Amaro Seoane, Zeyuan Xuan +3
Gravitational waves from a source moving relative to us can suffer from special-relativistic effects such as aberration. The required velocities for these to be significant are on…
Very extreme mass-ratio bursts in the Galaxy and neighbouring galaxies in relation to space-borne detectors
