IN recent years there has been a good deal of controversy about gravitational radiation. Historically, the position is as follows. It was shown quite soon after the publication of the general theory of relativity that the linear approximation to the field equations admits, in certain co-ordinate systems, solutions which have an obvious wave-like character; moreover, it appears from the energy pseudo-tensor that these waves carry energy away from the sources, as in the electromagnetic case… 
Gravitational Radiation
Talks on gravitational radiation at previous Texas Symposia have spanned a wide range of subjects, from efforts to detect gravitational waves to the mathematical questions concerning the quadrupole
Energy-momentum and asymptotic geometry
I show that radiative space-times are not asymptotically flat; rather, the radiation field gives rise to holonomy at null infinity. (This was noted earlier, by Bramson.) This means that, when
Gravitomagnetics, the Basics of a Simpler Approach
Galileo studied bodies falling under gravity and Tycho Brahe made extensive astronomical observations which led Kepler to formulate his three famous laws of planetary motion. All these observations
Theory of Gravitational Waves
The existence of gravitational radiation is a natural prediction of any relativistic description of the gravitational interaction. In this chapter, we focus on gravitational waves, as predicted by
Breaking of parallelograms in presence of torsion: an equivalent alternative approach to detect gravitational waves
The equations for gravitational plane waves produced by a typical binary system as a solution of linear approximation of Einstein equations are derived. The dynamics of the corresponding
Gravitomagnetic effects in the propagation of electromagnetic waves in variable gravitational fields of arbitrary-moving and spinning bodies
Propagation of light in the gravitational field of self-gravitating spinning bodies moving with arbitrary velocities is discussed. The gravitational field is assumed to be weak everywhere. Equations
The basics of gravitational wave theory
Einstein's special theory of relativity revolutionized physics by teaching us that space and time are not separate entities, but join as 'spacetime'. His general theory of relativity further taught
Gravitomagnetics a Simpler Approach Applied to Dynamics within the Solar System
Galileo studied bodies falling under gravity and Tycho Brahe made extensive astronomical observations which led Kepler to formulate his three famous laws of planetary motion. All these observations
Sources of gravitational waves in asymptotically flat Einstein-Maxwell spacetime
In this work, the dynamic of isolated systems in general relativity is described when gravitational radiation and electromagnetic fields are present. In this construction, the asymptotic fields
The Quantization of Linear Gravitational Perturbations and the Hadamard Condition
The quantum field theory describing linear gravitational perturbations is important from a cosmological viewpoint, in particular when formulated on de Sitter spacetime, which is used in inflationary
