Analytic Electromagnetic Effective Source for Geodesic Orbit in Schwarzschild Spacetime
Xuchen Lu, Yungui Gong, Bokai Zhang +2
Self-force effects are essential for accurately describing the motion of small bodies in curved spacetime. The effective-source approach privides a promising route to higher-order…
Frequency-domain extended-effective-source gravitational self-force for eccentric Schwarzschild orbits
Xuchen Lu, Yungui Gong, Bokai Zhang +2
Effective-source formulations provide a practical route to gravitational self-force (GSF) calculations when singular retarded fields cannot be handled directly mode by mode. Up to…
The point-particle-limit effective-source approach for computing gravitational self-force in the Lorenz gauge
Chao Zhang, Yungui Gong, Xuchen Lu +1
The traditional effective-source method is hampered by complex analytical expressions and the inherent smoothness limit, which incur high computational costs and complicate impleme…
Gravitational wave cosmology
Ligong Bian, Rong-Gen Cai, Yu-Qi Dong +18
Gravitational waves (GWs) originating from cosmological sources offer direct insights into the physics of the primordial Universe, the fundamental nature of gravity, and the cosmic…
Generic effective sources for first-order in mass-ratio gravitational self-force calculations in Schwarzschild spacetime
Chao Zhang, Rong-gen Cai, Guoyang Fu +3
The numerical calculation of gravitational self-force in extreme mass ratio inspiral systems is fundamentally challenging due to the singular nature of point-particle sources. To o…
Null tests with Gaussian Process
Shengqing Gao, Qing Gao, Yungui Gong +1
We investigate the null tests of spatial flatness and the flat CDM model using the Baryon Acoustic Oscillation (BAO) data measured by the Dark Energy Spectroscopic Instrument (D…
Potentialities of Hubble parameter and expansion rate function data to alleviate Hubble tension
Yingjie Yang, Xuchen Lu, Lei Qian +1
Taking advantage of Gaussian process (GP), we obtain an improved estimate of the Hubble constant, km s Mpc, using Hubble parameter [] from co…
