Accretion of a Plasma Vlasov Gas onto a Reissner-Nordström Black Hole
Yongqiang Liu, Hongsheng Zhang
We develop a steady-state, spherically symmetric accretion framework for a two-component plasma Vlasov gas in a Reissner-Nordström spacetime under a fixed background electromagnet…
Misner-Sharp Energy and P-V Criticality in Quasi-Topological Cosmology
Yue Chu, Shi-Bei Kong, Yang Liu +2
We presented a sound foundation of thermodynamics for a Friedmann-Robertson-Walker (FRW) universe from the first principle in ground-breaking work [Hu et al., JHEP12 (2022) 168]. B…
Strong lensing as a probe of braneworld
Yi Zhang, Hong Liu, Dan Wen +1
For the first time, we use the Event Horizon Telescope (EHT) data to constrain the parameters of braneworld black holes which constrain $ε=0.0285^{+0.0888+0.1456}_{-0.0895-0.1475}…
Energy in critical collapse
Yu Hu, Jun-Qi Guo, Junbin Li +2
We study the energy issue in critical collapse of a spherically symmetric scalar field. It is found that in critical collapse, the contribution from the material energy is greater…
