Constraints on Schwarzschild Black Hole in a Generalized Dehnen-Type Dark Matter Halo via the S2 Star Orbit around Sgr A
Tursunali Xamidov, Sanjar Shaymatov, Qiang Wu
The distribution of dark matter (DM) halo around supermassive black holes (BHs) may leave observable imprints on stellar dynamics near galactic centers. Motivated by this, we inves…
Gravitational wave signatures from periodic orbits around a Schwarzschild-Bertotti-Robinson black hole
Tursunali Xamidov, Sanjar Shaymatov, Qiang Wu +1
In this paper, we investigate periodic bound orbits and gravitational wave (GW) emission in the Schwarzschild-Bertotti-Robinson (Schwarzschild-BR) spacetime-an exact electrovacuum…
Signatures of Quantum-Corrected Black Holes in Gravitational Waves from Periodic Orbits
Fazlay Ahmed, Qiang Wu, Sushant G Ghosh +1
We investigate gravitational wave emission from periodic timelike orbits of a test particle around a loop quantum gravity-inspired Schwarzschild black hole. The spacetime is charac…
Probing Loop Quantum Gravity black holes through gravitational lensing
Arun Kumar, Qiang Wu, Tao Zhu +1
We investigate strong gravitational lensing by a charged loop quantum gravity (LQG) black hole obtained through the polymerisation scheme of Borges \textit{et al.} \cite{Borges:202…
Gravitational Wave Signatures from Periodic Orbits around a non-commutative inspired black hole surrounded by quintessence
Fazlay Ahmed, Qiang Wu, Sushant G Ghosh +1
We study gravitational wave emission from periodic orbits of a test particle around a noncommutative-inspired black hole surrounded by quintessence. Using the zoom-whirl taxonomy,…
Lyapunov Exponent Approach to Phase Structure of Schwarzschild AdS Black Holes Surrounded by a Cloud of Strings
Arun Kumar, Qiang Wu, Tao Zhu +1
We investigate Schwarzschild black holes in anti-de Sitter (AdS) spacetimes surrounded by a cloud of strings (BH-AdS-CoS), incorporating both electric- and magnetic-like components…
Epicyclic oscillations and accretion disk around a special Buchdahl-inspired spacetime
Mirzabek Alloqulov, Mubasher Jamil, Sanjar Shaymatov +2
In this paper, we consider the Buchdahl-inspired spacetime metric and investigate its aspects using the quasiperiodic oscillations and the accretion disk due to the accreting matte…
Probing the Schwarzschild black hole immersed in a dark matter halo through astrophysical tests
Tursunali Xamidov, Sanjar Shaymatov, Qiang Wu +1
We investigate a recently derived Schwarzschild-like black hole immersed in a Dehnen-type dark matter (DM) halo. We obtain constraints on the two model paramete…
The effects of asymptotically flat spacetime on black hole image of Sagittarius A*
Jian-Ming Yan, Tao Zhu, Qiang Wu
A new class of analytically expressible vacuum solutions has recently been discovered for pure gravity, building upon Buchdahl's seminal work from 1962. These solutions, in…
Shadows of Loop Quantum Black Holes: Semi-analytical Simulations of Loop Quantum Gravity Effects on Sagittarius A* and M 87*
Hong-Xuan Jiang, Cheng Liu, Indu K. Dihingia +4
In this study, we delve into the observational implications of rotating Loop Quantum Black Holes (LQBHs) within an astrophysical framework. We employ semi-analytical General Relati…
Accretion disk around Reissner-Nordström black hole coupled with a nonlinear electrodynamics field
G. Abbas, H. Rehman, Tao Zhu +2
The phenomenon by which matter accumulates in the vicinity of a huge celestial object is known as accretion. The gravitational energy is excreted as a consequence of infalling matt…
Constraints on the rotating self-dual black hole with quasi-periodic oscillations
Cheng Liu, Haiguang Xu, Hoongwah Siew +3
An impressive feature of loop quantum gravity (LQG) is that it can elegantly resolve both the big bang and black hole singularities. By using the Newman-Janis algorithm, a regular…
