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…
