Cylindrical systems in general relativity [PDF]

Classical and quantum gravity, 2019
With the arrival of the era of gravitational wave astronomy, the strong gravitational field regime will be explored soon in various aspects. In this article, we provide a general review over cylindrical systems in Einstein’s theory of general relativity.

Non-linear obstructions for consistent new general relativity [PDF]

Journal of Cosmology and Astroparticle Physics, 2019
We revisit the field content and consistency of the New General Relativity family of theories. These theories are constructed in a geometrical framework with a flat and metric-compatible connection, so the affine structure is entirely determined by the ...

Testing general relativity [PDF]

Proceedings of Gran Sasso Summer Institute 2014 Hands-On Experimental Underground Physics at LNGS — PoS(GSSI14), 2015
This lecture will present a review of the past and present tests of the General Relativity theory. The essentials of the theory will be recalled and the measurable effects will be listed and analyzed. The main historical confirmations of General Relativity will be described.

Relativity, Dimensionality, and Existence [PDF]

, 2007
The main purpose of this paper is to demonstrate that the analysis of the kinematical effects of special relativity holds the key to answering the question of the dimensionality of the world.

Conformally Coupled General Relativity

Universe, 2018
The gravity model developed in the series of papers (Arbuzov et al. 2009; 2010), (Pervushin et al. 2012) is revisited. The model is based on the Ogievetsky theorem, which specifies the structure of the general coordinate transformation group. The theorem

Decoupling gravitational sources in general relativity: The extended case [PDF]

Physics Letters B, 2018
We show how to decoupling two spherically symmetric and static gravitational sources through the most general possible extension of the so-called Minimal Geometric Deformation-decoupling.

Hierarchical Test of General Relativity with Gravitational Waves. [PDF]

Physical Review Letters, 2019
We propose a hierarchical approach to testing general relativity with multiple gravitational wave detections. Unlike existing strategies, our method does not assume that parameters quantifying deviations from general relativity are either common or ...

Numerical relativity simulation of GW150914 beyond general relativity [PDF]

Physical Review D, 2019
We produce the first astrophysically relevant numerical binary black hole gravitational waveform in a higher-curvature theory of gravity beyond general relativity.
