43. A treatment to gravitational perturbations and Lorentz-violating effects with Lagrangian analysis

Chao Zhang (China University of Petroleum, Beijing)

Since the first direct detection to the gravitational wave (GW), i.e., the event GW150914, it has emerged as a blockbuster during the past decade within the realm of theoretical physics. Specially, it provides us with an unprecedented opportunity in testing theories of gravity that beyond the scope of general relativity (GR), especially in the strong-field regime. One common way for extracting...

33. Beyond Symmetry-Reduced Models: Bouncing Cosmology, Regular Black Holes and Gravitational Waves from a Full Theory Perspective

Current research on quantum gravity inspired bouncing cosmologies and regular black holes, as well as their potential gravitational wave signatures, has largely relied on symmetry-reduced models, such as those assuming spherical symmetry. However, these simplified models may fail to capture essential physical features inherent in the full theory. It is therefore crucial to develop approaches...

31. Bouncing behaviour in non-commutative space-time

The non-commutative space-time structures, naturally incorporate the minimal length scale, carries the imprints of quantum gravity signals. We show that the kappa-Minkowski space-time, a Lie-algebraic type non-commutative space-time appearing in the low energy limit of loop quantum gravity, avoids the initial singularity in early universe by providing a bounce behaviour.

62. Numerical computation of electromagnetically sourced nonlinear tails

Zhen-Tao He

Amazingly, recent studies indicate that nonlinear effects are of great significance for modelling black hole ringdown. Transient electromagnetic events in the astrophysical environment are typically high-energetic, potentially responsible for some nonlinearities in ringdown. Motivated by the desire to understand these nonlinearities, we solve the inhomogeneous Bardeen-Press-Teukolsky equation...
