Construction of an analytic multi-component accretion environment and its application to Kerr black hole imaging
Shiyang Hu, Dan Li, Chen Deng +2
The construction of accretion environments is fundamental to black hole imaging. From a purely geometric perspective, we construct a novel analytic accretion environment comprising…
Rational Orbits and Gravitational Waves in Static Spherical Spacetimes: An Open-Source Numerical Framework
Dan Li, Shiyang Hu, Chen Deng +2
Timelike orbits constitute a crucial probe for exploring the intrinsic properties of curved spacetimes, and the carried gravitational radiation signals provide a direct window into…
Strong field gravitational lensing of particles by a black-bounce-Schwarzschild black hole
Guansheng He, Jiaxu Huang, Zhongwen Feng +2
The gravitational lensing of relativistic and nonrelativistic neutral massive particles in the black-bounce-Schwarzschild black hole spacetime is investigated in the strong deflect…
Leading-order gravitational time delay of massive particles by a moving Schwarzschild lens
Guansheng He, Wenbin Lin, Yi Xie
The leading-order gravitational time delay of relativistic neutral massive particles (e.g., neutrinos or high-energy cosmic-ray particles) caused by a moving Schwarzschild black ho…
Leading-order deflection of particles by a moving Schwarzschild lens with a two-dimensional velocity
Xuan Wang, Wenbin Lin, Ghulam Mustafa +1
The gravitational deflection effect of relativistic massive and massless particles up to the first post-Minkowskian order caused by a moving Schwarzschild black hole with a two-dim…
Gravitational deflection of light in polar-axis plane of a moving Kerr-Newman black hole
Xuan Wang, Wenbin Lin, Bo Yang +1
The gravitational deflection of light signals restricted in the polar-axis plane of a moving Kerr-Newman (KN) black hole with a constant velocity along the polar axis is studied wi…
