Influence of quantum decoherence on black hole shadow visibility and time domain echoes
Sen Guo, Xin Li, Yu Liang +2
The geometric shadow of a black hole cannot observationally distinguish horizonless exotic compact objects. We break this degeneracy by mapping the fundamental quantum decoherence…
Coherent multipath wave response on Reissner-Nordström analogue surface
Peng-Yu Chen, Sen Guo, Qing-Quan Jiang +2
To uncover how the intrinsic metric of a relativistic compact object governs macroscopic wave phenomena, we establish a theoretical framework mapping the charge dependent spatial g…
Stationary Dirac condensates around Kerr black holes
Sen Guo, Peng-Yu Chen, Yi-Han Huang +4
Ultralight bosonic fields can form macroscopic clouds around rotating black holes, whereas the existence of analogous stationary fermionic condensates is strictly constrained by th…
Optical Appearances of Accreting Ellis-Bronnikov Wormholes Observed from Both Sides of Throats
Yu-Hao Cui, Kai Lin, Sen Guo +2
This study investigates the optical appearance of the Ellis-Bronnikov wormhole as viewed from both sides of its throat, under conditions of optically thick and thin accretion. By s…
Gravitational waveforms from periodic orbits around Gauss-Bonnet black holes
Yi-Han Huang, Sen Guo, Yu Liang +2
Extreme mass-ratio inspirals (EMRIs) constitute one of the most promising probes of strong field gravity for future space borne gravitational-wave observatories. As a representativ…
Polarized Radiative Transfer of Kerr-Newman Black Hole
Xin Li, Sen Guo, Pei Wang +6
In this analysis, we investigate the polarization radiation imaging of Kerr-Newman black holes, with a particular focus on the impact of black hole charge on photon propagation and…
Image of a time-dependent rotating regular black hole
Sen Guo, En-Wei Liang, Yu-Xiang Huang +4
In this study, we develop a modeling framework based on spatio-temporal generalized random fields to simulate the time-evolving accretion flows and their associated imaging signatu…
Image of the time-dependent black hole
Yu Liang, Sen Guo, Kai Lin +3
The Event Horizon Telescope's 2024 observations report a shift in the position angle of the brightness asymmetry in M87*, revealing time variability in the black hole's image. In t…
Image of the Kerr-Newman black hole surrounded by a thin accretion disk
Sen Guo, Yu-Xiang Huang, En-Wei Liang +3
The image of a Kerr-Newman (KN) black hole (BH) surrounded by a thin accretion disk is derived. By employing elliptic integrals and ray-tracing methods, we analyze photon trajector…
Optical appearance of numerical black hole solutions in higher derivative gravity
Yu-Hao Cui, Sen Guo, Yu-Xiang Huang +2
The optical appearance of the numerically black hole solutions within the higher derivative gravity illuminated by an accretion disk context is discussed. We obtain solutions for n…
Rastall gravity: accretion disk image in radiation fields context and visual transformations compared to Reissner-Nordstrom black holes
Yu-Xiang Huang, Sen Guo, Yu Liang +3
Our study investigates the astronomical implications of Rastall gravity, particularly its behavior amidst a radiation field compared to Reissner-Nordstrom (RN) black holes. Our res…
