Constraining parity and Lorentz violations in gravity with future ground- and space-based gravitational wave detectors
Bo-Yang Zhang, Tao Zhu, Jian-Ming Yan +2
The future ground- and space-based gravitational wave (GW) detectors offer unprecedented opportunities to test general relativity (GR) with greater precision. In this work, we inve…

Modified gravitational wave propagations in linearized gravity with Lorentz and diffeomorphism violations and their gravitational wave constraints
Qiang Wang, Jian-Ming Yan, Tao Zhu +1
The standard model extension (SME) is an effective field theory framework that can be used to study the possible violations of Lorentz symmetry and diffeomorphism invariance in the…

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…
