Scientific Reports, 2023 Spacecraft operating in low orbit are at risk of being hit by space debris. In the debris environment, the impact of debris is likely to cause the double satellite formation to exit science mode or even lead to the divergence of the control system, thus ...

The velocity of gravitational waves [PDF]
Physics Letters A, 1999 We examine the propagation of gravitational waves in the new field theory of gravitation recently proposed by Novello-De Lorenci-Luciane (NDL). This examination is done on a solvable case corresponding to a spherically symmetric static configuration. We show that in NDL theory the velocity of gravitational waves is lower than light velocity.

Diagrammatic Effective Field Theory Approach to Coalescing Binary Systems in General Relativity and Gravitational Waves Phenomenology [PDF]
, 2023 openIn this thesis we study the dynamics of a gravitationally bound binary system composed of two spinless compact objects, which could be black holes or neutron stars, in the post-Newtonian (PN) approximation scheme of general relativity.

Detection of gravitational waves by light perturbation
European Physical Journal C: Particles and Fields, 2021 Light undergoes perturbation as gravitational waves pass by. This is shown by solving Maxwell’s equations in a spacetime with gravitational waves; a solution exhibits a perturbation due to gravitational waves.

The search for gravitational waves [PDF]
Journal of Physics B: Atomic, Molecular and Optical Physics, 2005 Experiments aimed at searching for gravitational waves from astrophysical sources have been under development for the last 40 years, but only now are sensitivities reaching the level where there is a real possibility of detections being made within the next five years.

Journal of High Energy PhysicsWe study the decays of B (s) mesons into light pseudoscalar mesons under the SU(3) flavour symmetry. Assuming exact SU(3) symmetry at the level of the amplitudes leads to a simple parametrisation.
