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.

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.

Gravitational Waves. Introduction to the Gravitational Wave Equation

, 2023
Gravitational Waves represent the transport of Gravitational Energy through Space. Equation (103) represents the “Gravitational Wave Equation”. The article presents a new theory in physics which explains the interaction between gravity and light with mathematical results close to General Relativity (15 digits beyond the decimal point equal result) and

Lunar Gravitational-wave Antenna

The Astrophysical Journal, 2021
Abstract Monitoring of vibrational eigenmodes of an elastic body excited by gravitational waves was one of the first concepts proposed for the detection of gravitational waves. At laboratory scale, these experiments became known as resonant bar detectors first developed by Joseph Weber in the 1960s.

Geometric Approach to Analytic Marginalisation of the Likelihood Ratio for Continuous Gravitational Wave Searches

Universe, 2021
The likelihood ratio for a continuous gravitational wave signal is viewed geometrically as a function of the orientation of two vectors; one representing the optimal signal-to-noise ratio, and the other representing the maximised likelihood ratio or F ...
