Spin precession in the strong deflection limit
Jiafei Geng, Yunchuan Xiang, Qingquan Jiang +1
The strong deflection limit (SDL) of the deflection angle is well established for general spherically symmetric spacetimes, but a systematic SDL treatment of spin precession has be…
Fermionic Love number of higher-dimensional Reissner-Nordström black holes
Xiankai Pang, Yu Tian, Hongbao Zhang +1
In this paper, we generalize our previous work on the fermionic tidal Love numbers (TLNs) to higher-dimensional Reissner-Nordström black holes. The massless Dirac equation is solv…
Fermionic Love number of Reissner-Nordström black holes
Xiankai Pang, Yu Tian, Hongbao Zhang +1
The tidal deformation of compact objects, characterised by their Love numbers, provides insights into the internal structure of neutron stars and black holes. While static bosonic…
A Novel Pipeline for the Identification of New Gamma-Ray Blazars from the 4FGL-Xiang-DR2 Catalog Based on Multi-wavelength Flux Distributions
Yunchuan Xiang, Yingzhi Ye, Peng Feng +5
The identification and classification of Fermi blazars are core topics in high-energy astrophysics. To enable precise spatial cross-identification, we constructed two high-precisio…
The precession of particle spin in spherical symmetric spacetimes
Xiankai Pang, Qingquan Jiang, Yunchuan Xiang +1
In this work, we will explore the precession of particle spins in spherical spacetimes. We first argue that the geometrical optics (WKB) approximation is insufficient, due to the a…
