Does DESI prefer Damped Oscillating Dark Energy over Cosmological constant?
Saddam Hussain, Simran Arora, Qiang Wu +1
We investigate a dark-energy equation of state governed by a damped harmonic oscillator equation, admitting underdamped, critically damped, and overdamped solutions. Confronting th…
Spinning Primordial Black Holes and Scalar Induced Gravitational Waves from Single Field Inflation
Abolhassan Mohammadi, Yogesh, Qiang Wu +1
We investigate the formation of primordial black holes (PBHs), their spin and abundance, in a single-field inflationary model based on a mutated hilltop potential inserted with a s…
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…
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…
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…
Strong Gravitational Lensing by Static Black Holes in Effective Quantum Gravity
Yiyang Wang, Amnish Vachher, Qiang Wu +2
We investigate strong gravitational lensing by two static black hole models (Model-1 and Model-2) within the Effective Quantum Gravity (EQG) framework, characterized by mass an…
Enhanced Blandford Znajek Jet in Loop Quantum Black Hole
Hong-Xuan Jiang, Indu K. Dihingia, Cheng Liu +2
The Blandford-Znajek (BZ) process powers energetic jets by extracting the rotating energy of a Kerr black hole. It is important to understand this process in non-Kerr black hole sp…
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…
Constraints on Hairy Kerr black hole with quasi-periodic oscillations
Cheng Liu, Hoongwah Siew, Tao Zhu +3
The Hairy Kerr black hole is a novel black hole solution that depicts a rotating space-time encompassed by an axisymmetric fluid. It has significant observational importance and is…
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…
