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…
Superradiant Bose--Einstein condensates around Kerr black holes
Sen Guo, Lin Wen, Xiao-Xiong Zeng
Ultralight bosonic dark matter can accumulate around a rotating black hole, where superradiance amplifies the field until a macroscopic cloud forms. Whether such a cloud behaves as…
Optical Images of the Braneworld Black Hole Surrounded by an Optically Thin Accretion Disk
Wen-Hao Deng, Sen Guo, Qing-Quan Jiang +2
This work examines the observational signatures of rotating black holes with tidal charge in the Randall--Sundrum braneworld scenario. Combining an elliptic-integral-based analytic…
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…
Polarization Signatures of Rotating Black Holes in Perfect Fluid Dark Matter Spacetimes
Yu-Xiang Huang, Sen Guo, En-Wei Liang +2
Motivated by horizon-scale polarization observations of M87^{*}, we investigate polarized emission from rotating black holes (BHs) immersed in a perfect fluid dark matter (PFDM) ba…
What does a regular star look like?
Yu Liang, Yuhao Cui, Kai Lin +5
Recently, astronomers discovered unusual Einstein cross images of the galaxy HerS-3, which feature a bright central spot. Motivated by studies of images produced by regular stars,…
Impact of Perfect Fluid Dark Matter on the Appearance of Rotating Black Hole
Huang Yu-Xiang, Guo Sen, Liang En-Wei +1
Understanding how dark matter affects the immediate environment of black holes (BHs) is crucial for interpreting horizon-scale observations. We study rotating BHs surrounded by per…
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…
