Population statistics of nanohertz gravitational wave sources
Jiming Yu, Zhen Pan, Xiao Xue +1
The recent detection of a nanohertz gravitational wave (GW) background by pulsar timing arrays (PTA) has sparked extensive discussions regarding its origin-whether it arises from a…
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…
Probing Fundamental Constant Oscillation in the Galactic Center with S-Star Spectroscopy
Zhaoyu Bai, Vitor Cardoso, Yifan Chen +5
Astrophysical spectroscopy provides a powerful probe of spacetime variations of fundamental constants, as atomic and ionic emission and absorption lines depend sensitively on the f…
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…
