Multiscale probing of a Hernquist-type environmental black hole spacetime with the Sgr A* shadow and S2 orbital dynamics
Lai Zhao, Meirong Tang, Zheng-Wen Long +1
The supermassive black hole Sgr A* at the Galactic center provides a unique opportunity to probe the distribution of environmental matter around black holes. In this work, we adopt…
Constraints on the Scale Parameter of Regular Black Hole in Asymptotically Safe Gravity from Extreme Mass Ratio Inspirals
Lai Zhao, Meirong Tang, Zhaoyi Xu
This paper evaluates the potential for constraining the quantum scale parameter of regular black hole within the asymptotically safe gravity framework using gravitational wave…
Shadow constraints of charged black hole with scalar hair and gravitational waves from extreme mass ratio inspirals
Lai Zhao, Meirong Tang, Zhaoyi Xu
Black hole (BH) shadow observations and gravitational wave astronomy have become crucial approaches for exploring BH physics and testing gravitational theories in extreme environme…
Strong Gravitational Lensing Effects of the Rotating Short-Haired Black Hole and Constraints from EHT Observations
Lai Zhao, Meirong Tang, Zhaoyi Xu
For the short hairs that have a significant impact only near the event horizon, studying their strong gravitational lensing effects is of great significance for revealing the prope…
Periodic orbits and gravitational wave radiation in short hair black hole spacetimes for an extreme mass ratio system
Lai Zhao, Meirong Tang, Zhaoyi Xu
For a short hair black hole(BH) which circumvents the "no-short-hair" theorem, it manifests intense hair behavior in the vicinity of the event horizon, accompanied by remarkable qu…
Test the weak cosmic censorship conjecture via black hole in dark matter halo
Meirong Tang, Lai Zhao, Zhaoyi Xu
The weak cosmic censorship conjecture states that the black hole singularity is hidden inside the event horizon of the black hole, making it impossible for an external observer to…
