Correspondence between multileaf topology of closed geodesics and spatiotemporal autocorrelations of hotspot images in Schwarzschild spacetime
Fengting Xie, Qing-Hua Zhu, Xin Li
The classification of relativistic closed orbits by their multileaf structures provides a framework for studying strong-field dynamics. Identifying these structures in astronomical…
Detectability of secondary images from flares near Sgr A* with mock GRAVITY data
Fengting Xie, Qing-Hua Zhu, Xin Li
The orbital motion of near-infrared flares reported by the GRAVITY collaboration encodes information about both the dynamics of accretion matter and the underlying spacetime geomet…
Exploring the statistical anisotropy of primordial curvature perturbations with pulsar timing arrays
Fengting Xie, Zhi-Chao Zhao, Qing-Hua Zhu +1
The recent detection of a stochastic gravitational wave background by pulsar timing arrays has opened a new window in understanding supermassive black hole binaries and in probing…
Investigating non-Keplerian motion in flare events with astrometric data
Fengting Xie, Qing-Hua Zhu, Xin Li
The GRAVITY interferometer has achieved microarcsecond precision in near-infrared interferometry, enabling the tracking of flare centroid motion in the strong gravitational field n…
