Probing Hernquist dark matter through the optical appearance of black holes: A comprehensive study of various accretions
Yuxuan Shi, Hongbo Cheng
The observational appearance of a black hole is critically dependent on the surrounding accreting matter, in particular on the central brightness depression and photon ring structu…
The Barrow entropies in the thermodynamics of high-dimensional Gauss-Bonnet black holes
Yuxuan Shi, Hongbo Cheng
We study the thermodynamics of -dimensional Gauss-Bonnet black holes with Barrow entropy. It is found that the Gauss-Bonnet coupling and the Barrow factor revise the thermodynam…
The indivisibility of a quantum-corrected AdS black hole with phantom global monopoles
Tiantong Cheng, Hongbo Cheng
We study the indivisibility of a quantum-corrected AdS black hole involving two kinds of global monopoles, regular or phantom ones to declare the effects from the quantum fluctuati…
The validity of the universal relation between corrections to entropy and the extremality of Schwarzschild-de Sitter black holes under the GUP and EUP
Hongbo Cheng, Yinan Zhao
We investigate the extremality relations by examining perturbative corrections to both the entropy of Schwarzschild-de Sitter black holes and their extremality bounds under the Nar…
The accretion disk and neutrino propagation of Barrow-modified Black Hole
Yuxuan Shi, Hongbo Cheng
This paper attempts to clarify the deep consequences of Barrow fractal black hole spacetime configurations caused by quantum gravity on neutrino pair annihilation and accretion dis…
The neutrino flavor oscillations in the static and spherically symmetric black-hole-like wormholes
Yuxuan Shi, Hongbo Cheng
We study the effects of neutrino lensing induced by a Damour-Solodukhin wormhole on the neutrino oscillation. We derive and calculate the flavour transition probabilities in the pr…
