Inference on inner galaxy structure via gravitational waves from supermassive binaries
Yifan Chen, Matthias Daniel, Daniel J. D'Orazio +107
The detection of a stochastic gravitational wave background by pulsar-timing arrays indicates the presence of a population of supermassive black hole binaries. Although the observe…

Identifying the Quadrupolar Nature of Gravitational Wave Background through Space-based Missions
Yifan Chen, Yuxiang Liu, Jing Shu +3
The stochastic gravitational wave background (SGWB) consists of an incoherent collection of waves from both astrophysical and cosmological sources. To distinguish the SGWB from noi…

Non-Gaussian Statistics of Nanohertz Stochastic Gravitational Waves
Xiao Xue, Zhen Pan, Liang Dai
Recent detection of nHz stochastic gravitational wave background (SGWB) by multiple pulsar timing arrays (PTAs) has stimulated intensive discussions about its physical origin. In p…
