On the parameters of the spherically symmetric parametrized Rezzolla-Zhidenko spacetime through solar system tests, orbit of S2 star about Sgr A, and quasiperiodic oscillations
Sanjar Shaymatov, Bobomurat Ahmedov, Mariafelicia De Laurentis +4
In this paper, we find the higher order expansion parameters and of spherically symmetric parametrized Rezzolla--Zhidenko (PRZ) spacetime by using its functions of the radi…
Gravitational wave constraints on non-birefringent dispersions of gravitational waves due to Lorentz violations with GWTC-3
Cheng Gong, Tao Zhu, Rui Niu +5
The standard model extension (SME) is an effective field theory framework that can be used to study the possible violations of Lorentz symmetry in the gravitational interaction. In…
Observational tests of quantum extension of Schwarzschild spacetime in loop quantum gravity with stars in the galactic center
Jian-Ming Yan, Cheng Liu, Tao Zhu +2
In this paper, we use the publicly available observational data of 17 stellar stars orbiting Sgr A* to test the quantum extension of Schwarzschild spacetime in loop quantum gravity…
Pion parton distribution functions with the nonrelativistic constituent quark model
Qian Wu, Chengdong Han, Di Qing +4
We calculate the valence quark distribution functions of the meson using the non-relativistic chiral constituent quark model. The wave function is obtained by solving the t…
Equatorial and polar quasinormal modes and quasiperiodic oscillations of quantum deformed Kerr black hole
Kimet Jusufi, Mustapha Azreg-Aïnou, Mubasher Jamil +1
In this paper we focus on the relation between quasinormal modes (QNMs) and a rotating black hole shadows. As a specific example, we consider the quantum deformed Kerr black hole o…
Constraints on self-dual black hole in loop quantum gravity with S0-2 star in the Galactic Center
Jian-Ming Yan, Qiang Wu, Cheng Liu +2
One of remarkable features of loop quantum gravity (LQG) is that it can provide resolutions to both the black hole and big bang singularities. In the mini-superspace approach based…
Are the black hole remnants produced from binary black hole mergers in GWTC-3 thermodynamically stable?
Qiang Wu, Shao-Wen Wei, Tao Zhu
Black hole thermodynamics has brought strong hints of a profound and fundamental connection between gravity, thermodynamics, and quantum theory. If the black hole does behave like…
Gravitational wave constraints on Lorentz and parity violations in gravity: high-order spatial derivative cases
Cheng Gong, Tao Zhu, Rui Niu +5
High-order spatial derivatives are of crucial importance for constructing the low energy effective action of a Lorentz or parity violating theory of quantum gravity. One example is…
Constraints on the Nieh-Yan modified teleparallel gravity with gravitational waves
Qiang Wu, Tao Zhu, Rui Niu +2
The discovery of gravitational waves (GWs) from the compact binary components by LIGO/Virgo Collaboration provides an unprecedented opportunity for testing gravity in the strong an…
Preinflationary dynamics in loop quantum cosmology: Monodromy Potential
Manabendra Sharma, M. Shahalam, Wu Qiang +1
In this article we explore the pre-inflationary background dynamics of an FLRW universe sourced by a scalar field with monodromy potential in LQC framework. In particular we calcul…
