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…
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…
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,…
Interacting -essence field with non-pressureless Dark Matter: Cosmological Dynamics and Observational Constraints
Saddam Hussain, Qiang Wu, Tao Zhu
We investigate a class of interacting dark energy and dark matter (DM) models, where dark energy is modeled as a -essence scalar field with an inverse-square potential. Two gene…
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…
Starobinsky like inflation and EGB Gravity in the light of ACT
Yogesh, Abolhassan Mohammadi, Qiang Wu +1
The ACT data shows an enhancement in the value of the scalar spectral index, as , leading to disfavoring many inflationary models, including the Starobinsk…
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…
