GRAVITATIONAL RADIATION AND GENERAL RELATIVITY

Le Journal de Physique Colloques, 1973
The basic properties of gravitational radiation, as predicted by general relativity, are described and compared with those of electromagnetic radiation. Some recent results on radiative processes in the vicinity of black holes are outlined. It is stressed that some of these processes lead to more efficient methods of converting rest mass into radiative

The relativity of inertia and reality of nothing [PDF]

, 2008
The determination of inertia by matter is looked at in general relativity, where inertia can be represented by affine or projective structure. The matter tensor T seems to underdetermine affine structure by ten degrees of freedom, eight of which can be ...

Do the gravitational corrections to the beta functions of the quartic and Yukawa couplings have an intrinsic physical meaning?

Physics Letters B, 2017
We study the beta functions of the quartic and Yukawa couplings of General Relativity and Unimodular Gravity coupled to the λϕ4 and Yukawa theories with masses.

Gravitational clock compass in general relativity [PDF]

Physical Review D, 2018
We show how a suitably prepared set of clocks can be used to determine all components of the gravitational field in General Relativity. We call such an experimental setup a clock compass, in analogy to the usual gravitational compass. Particular attention is paid to the construction of the underlying reference frame.

Extended Theories of Gravitation

EPJ Web of Conferences, 2013
Extended theories of gravitation are naturally singled out by an analysis inspired by the Ehelers-Pirani-Schild framework. In this framework the structure of spacetime is described by a Weyl geometry which is enforced by dynamics.

Tidal Deformability of Neutron Stars in Scalar-tensor Theories of Gravity

The Astrophysical Journal, 2023
Gravitational waves from compact binary coalescences are valuable for testing theories of gravity in the strong field regime. By measuring neutron star tidal deformability using gravitational waves from binary neutron stars, stringent constraints were ...

An Isotropic Cosmological Model with Aetherically Active Axionic Dark Matter

Universe
Within the framework of the extended Einstein–aether–axion theory, we studied the model of a two-level aetheric control over the evolution of a spatially isotropic homogeneous Universe filled with axionic dark matter. Two guiding functions are introduced,

Gravitational waves in New General Relativity

Journal of Cosmology and Astroparticle Physics
Abstract The models of New General Relativity have recently got attention of research community, and there are some works studying their dynamical properties. The formal aspects of this investigation have been mostly restricted to the primary constraints in the Hamiltonian analysis.
